I. INTRODUCTION
Thank you for choosing your Model ARS-4 multi-stage regulator. This regu-
lator has been designed to maximize the charging efficiency of your Balmar
high-output alternator, and can also be used with many other P-type,
externally regulated alternators.
The ARS-4 is pre-programmed at the factory for universal, "out-of-the-
box" operation with most batteries. Built-in selectable programs
for Deep-Cycle Lead Acid, AGM, Gel and Optima battery
types are also available. Manual equalization, required for
some battery types, is also available. The ARS-4 offers the
ability to monitor and respond to alternator over-tempera-
ture conditions, when combined with optional alternator
temperature sensor (MC-TS-A).
II. INSTALLATION
1.      Mount the regulator in a dry, well-ventilated place, away from areas of excess
        heat and/or vibration. Avoid locations where regulator or wiring connections                                               CAUTION
        could be exposed to sprayed water or coolant.                                                                  The following instructions

        ulator (see Figure 1). Connect the second ground wire (BLACK) to the Data                                      experienced marine electri-
        Ground terminal. See Figure 4 on Page 2 for location.                                                          cal installers. If you are not
3.      The BROWN (ignition) wire activates the regulator. Attach the BROWN                                            experienced at installing
        wire to a switched +12VDC source. The ignition switch or an independent                                        electrical system compo -
        (ungrounded) oil pressure switch are both acceptable connection points. A                                      nents, we recommend the
        toggle switch may be added to this circuit to shut down the alternator manu-                                   use of a qualified marine
        ally when increased propulsion is needed.                                                                      electrical technician.
4.      Attach the RED wire in a location where it will sense the battery
        being charged. Likely connections include: 1) at the alternator's
        positive output, 2) at the common side of a battery selector
        switch (multi-battery banks), or 3) at the positive battery termi-
        nal (single battery bank). WHEN USING A BATTERY ISOLA-
        TOR, THE RED SENSE WIRE MUST BE CONNECTED
        ON THE BATTERY SIDE OF THE ISOLATOR, at the termi-
        nal supplying charging current to the larger battery bank.
 If using a dual-output alternator, the RED wire must connect to one of
the alternator output posts. If battery banks are unequal in size, connect
at the larger battery bank. If the smaller battery shows signs of over-
charging, move the RED wire to the alternator post supplying the
smaller battery. The RED wire carries up to 6 amps and is equipped
with a built-in 10-amp "mini" fuse and holder. If lengthening of the
RED wire beyond eight feet is necessary, increase wire size to 12-gauge.
                                                                                                     Figure 1 - Regulator wiring harness.

II. INSTALLATION (CONTINUED)
5.      Connect the two BLACK ground wires at the preferred ground at the
        rear of the alternator (see Figure 2 for typical alternator ground connec-
        tion).
6.      Connect duplex plug with BLUE and WHITE wires to the alternator.
        Some alternators may require ring terminal connections. If your alterna-
        tor doesn't provide for a plug connection, see your alternator manual for
        installation instructions.
        If your system utilizes a mechanical tachometer, the stator wire will not
        be used. DO NOT CONNECT THE STATOR WIRE TO THE REG-
        ULATOR UNDER THAT CIRCUMSTANCE.
8.      Attach optional Alternator Temp Sensor to the Alternator Temp Sensor            Figure 2 - Ground attachment.
        terminals shown in Figure 5. OBSERVE POLARITY. Attach sen-
        sor to alternator case as shown in Figure 3.
        Installing a toggle switch between the positive and negative wires of
        the Alternator Temperature Sensor cable allows you to reduce alter-
        nator output and horsepower load by 50% (Small Engine Mode).
9.      The Dash Lamp terminal provides a circuit for dash mounted visual
        or audible system warnings. Terminal output is 500Mil-Amps
        (0.50A) negative when activated by low voltage (12.8V), high voltage
        (1V over bulk), or high alternator temp (225F). Typical installation
        would include an incandescent, LED or audible alarm connected, at
        one side, to a source of 12-volt positive and the second terminal con-
        nected to the dash lamp circuit at the regulator. When a condition
        matching those mentioned above occurs, the lamp circuit goes to              Figure 3 - Optional Alternator
        ground, completing the circuit and activating the alarm.                     Temperature Sensor.

III. OPERATION
Once the regulator is properly installed and connected to
the rest of the charging system, it is ready to use. During
operation, a bank of eight (8) color-coded LED lights will       G G G G A                           R       A       A
be illuminated to provide programming, mode, diagnostic
and advisory information. At start-up, all eight LED lights Figure 6 - Indicates system start-up.
will illuminate for approximately three seconds (Figure 6).
Arrows indicate illuminated LEDs.
The initial display will be followed by a display which
indicates battery program type (Figure 7). Out of the box,       G G G G A                           R       A       A

Figure 10 for illustration of program settings as indicated
at start up.                                                Figure 8 - Indicates charging stage. (Start delay shown.)
The display will then cycle through the
various charging stages (Figure 8). Single
green LED furthest from the amber LED
indicates 45-second start delay. Two illu-
minated green LEDs indicate soft ramp
and bulk charging stage. Three illuminat-
ed green LEDs indicate absorption stage.
Four illuminated green LEDs indicate
float stage. See Figure 9 for illustration of
charging stages as indicated by the ARS-4
display during normal start-up operation.
During normal operation, the regulator
will delay alternator start-up for 45 sec-
onds to allow belts to seat and engine
lubrication to occur. After the initial start
delay, the regulator will ramp to charging
voltage over a one-minute period.
Once bulk charging voltage is reached, the
regulator will remain in the bulk stage for Figure 9 - Stages of charge as
a minimum of 36 minutes. At the end of shown during normal operation.

Once in absorption stage, the regulator wil remain at absorption voltage for a min-
imum of 120 minutes. Additional 6-minute increments will be added thereafter until target voltage is attained.
Regulator will remain in float stage for a minimum of six hours, after which, it will cycle back to absorption stage for a
minimum of 36-minutes. This cycle will continue throughout engine operation.
NOTE: THE REGULATOR WILL AUTOMATICALLY RETURN TO THE BEGINNING OF THE CHARGING
PROGRAM IF THE ENGINE IS SHUT DOWN AND RE-STARTED.

IV.     BASIC PROGRAMMING
ARS-4 regulators are factory preset for universal, "plug-and-play" operation with most
battery types. In addition to the default factory program, both models feature selectable
programs for Deep-Cycle flooded, AGM, Gel and Optima battery types. (A list of
detailed voltage and time values for the various presets is available on the Page 2, see
Figure 4.) A magnetic reed switch, located beside the first green LED enables user
adjustment. The switch works in two specific actions, as described in the box at right.
To select a program for your battery type:
1.    Turn ignition key to it's ON position. Allow the regulator to cycle through the
      45-second start delay and into the ramp-up/bulk stage (indicated by the two illu-
      minated green LEDs).
2.    Using the supplied magnetic screwdriver (as shown in Figure 11), Activate-Hold
      as discussed in the shaded box below. The #5 amber light and #6 flashing red            Figure 11 - Magnetic reed
      light will illuminate to indicate switch activation (Figure 12).                        switch / LED location.

3.    The red LED will stop flashing and the #7 amber light will illuminate shortly         and make adjustments.
      thereafter to indicate the battery preset program mode is engaged (Figure 13).
4.    As you continue to hold, the green lights on the left half of the LED display will be illuminated one-by-one to
      indicate battery type. The first green LED on the left will indicate Program 1 (Universal Factory Program). As
      you continue to hold the magnet to the switch, the display will cycle to the first two green LEDs (indicating
      Program 2 - Deep Cycle), three green LEDs (indicating Program 3 - Gel),
      four green LEDs (indicating Program 4 - AGM), or a single green LED
      closest to amber LED (indicating Program 5 - Optima). See Figure 13 at
      right.
5.    When the desired preset program is indicated, release the reed switch by
      removing your magnetic tool from the switch. Once a preset has been
      selected and the switch has been deactivated, the #5 amber light will go
      out, indicating that the switch has been deactivated. The green LED lights
      will remain for several second before going out (Figure 12).
6.    Once the green lights have gone out, you may change your selection by re-
      applying the magnet to the switch.
      The program choices will scroll in
      reverse order. Note: Keep in mind       `ACTIVATE-RELEASE' Refers

V.    ADVANCED PROGRAMMING
Advanced Programming provides the ability to modify factory preset programs
to meet specific charging needs. Advanced programming includes system volt-
age adjustment, system time adjustment, and equalization (time and voltage)
adjustment. (Equalization is only suggested for batteries noted as "equalization
friendly" in Figure 5 on Page 2). Consult your battery manufacturer for equal-
ization time and voltage recommendations.
Equalization must be initiated through the advanced programming mode. It is
NOT a standard mode of operation. Both EQ time and voltage must be set for
equalization to occur. Equalization will occur immediately after the program
has been saved into memory. EQUALIZATION VALUES MUST BE SET
WHILE ENGINE IS RUNNING.
Once equalization is complete, the regulator will return to its preset program
mode. NOTE: Advanced Programming modifications can be removed from the
regulator's memory by reselecting the original program for your battery type.
NOTE #2: The Advanced Programming Mode will cycle three times before sav-
ing new settings to memory. To enter to Advanced programming mode:
1.    ACTIVATE-HOLD the magnetic reed switch. LED #5 will illuminate and       Figure 14 - LED display protocol
      LED #6 will flash several times (Figure 14).                             indicating entry into advanced

      mode, as shown in Figure 16, ACTIVATE-HOLD the switch with your
      magnet. The display will cycle up through the values shown in Figure
      16. NOTE: To reverse scrolling direction, release the switch, wait until
      the green lights turn off, and re-activate and hold the switch to cycle the
      opposite direction. Keep in mind that the display has been programmed
      to provide approximately five seconds between value changes.
2.    When the display indicates your desired system time adjustment, release
      the switch.
3.    After several seconds, the green LEDs will turn off.
4.    If no changes are made to your selection, the #7 and #8 (amber) lights
      will flash once, indicating that your selection has been accepted. The dis-
      play will advance to the Equalization Voltage Adjustment mode.


VIII. EQUALIZATION VOLTAGE
The onset of sulfation can be lessened in some battery types by periodic intro-
duction of elevated voltage to the battery. See Figure 4 on Page 2 to determine
if your battery type will benefit from equalization. Voltage values are based on
system voltages determined by your preset program. CAUTION: Consult with
your battery manufacturer for recommended equalization time and voltage.
Both time and voltage values must be set for equalization to occur.
NOTE: EQUALIZATION TIME AND VOLTAGE MUST BE SET WITH
THE ENGINE RUNNING. ONCE EQUALIZATION HAS BEGUN, THE
DISPLAY WILL SHOW ALL FOUR GREEN LIGHTS AND THE #6 RED
LIGHT.
1.    When the LED indicates entry into the EQ Voltage mode, as shown in
      Figure 17, ACTIVATE-HOLD the switch with your magnet. The dis-
      play will show system voltage. When you activate the switch, the display
                                                                                    Figure 16 - LED display indicating

      the process will scroll downward.
2.    When the display indicates your
      desired EQ voltage value,
      RELEASE the switch.
3.    After several seconds, the green
      indicator lights will turn off.
4.    If no changes are made to your
      selection, the #6 red and #7 amber
      lights will flash once, indicating
      that your selection has been
      accepted. The display will advance
      to the Equalization Time
      Adjustment mode.

IX. EQUALIZATION TIME
The final mode in the Advanced Programming cycle is Equalization Time
Adjustment. To change the duration of EQ time:
1.    When the LED display indicates entry into the Equalization Time
      Adjustment mode, as shown in Figure 18, ACTIVATE-HOLD the switch
      with your magnet. The display will show the system default time. Release
      the switch, wait for the green light to go out, and re-activate/hold switch.
      Equalization Time Adjustment values will scroll through the values
      shown in Figure 18. Reversing the process will scroll downward.
2.    When the display indicates your desired EQ time value, release the
      switch.
3.    After several seconds, the green indicator lights will turn off.
4.    If no changes are made to your selection, the lights will flash once, indi-
      cating that your selection has been accepted. The Advanced Programming
      display will cycle two more times. If no other changes are made to your
      programming selections, the changes will be saved. A flashing #8 amber
      LED at the end of the final cycle indicates that your Advanced
      Programming selections have been saved.
5.    Equalization will occur immediately after the EQ time and voltage values
      have been saved into memory. Once equalization is completed, the regula-
      tor will return to regular charge mode governed by your preset battery
      program. CAUTION: Contact your battery manufacturer for recommend-
      ed EQ time and voltage values. Do not attempt equalization unless recom-
      mended by the battery manufacturer.
ADVANCED PROGRAMMING FOR SYSTEM VOLTAGE AND SYSTEM
TIME FUNCTIONS WILL REMAIN IN THE REGULATOR'S MEMORY
UNTIL THEY ARE MODIFIED WITHIN ADVANCED PROGRAMMING,
OR UNTIL THE PRESET PROGRAM FOR BATTERY TYPE IS RE-
SELECTED.
CAUTION: EQUALIZATION VOLTAGE MAY EXCEED THE LIMITS OF
SOME VOLTAGE SENSITIVE ONBOARD ELECTRONICS. EXTREME
CARE SHOULD BE EXERCISED TO ENSURE THAT ANY SENSITIVE
EQUIPMENT IS TURNED OFF AND/OR DISCONNECTED FROM
YOUR ELECTRICAL SYSTEM BEFORE EQUALIZATION TAKES
PLACE.                                                                               Figure 18 - LED display indicating

ARS-4 multi-stage regulators are equipped to provide diagnostic information via the LED display. To access diagnostic
data:
1.    After the basic display mode (see Section III) has cycled through its initial start-up, ACTIVATE-RELEASE the
      magnetic switch with your magnetic tool.
2.    The #6 red LED will begin to flash as the regulator scans through its diagnostic circuit.
3.    When the regulator senses a situation requiring attention, the flashing #6 red LED will alternate with specific
      groupings of green LED lights.
4.    Each LED grouping will corre-
      spond to a condition described in
      Figure 19. Each code will be
      displayed for several seconds, at
      which point, the regulator will
      continue to search for additional
      conditions.
5.    After all warning/advisory codes
      are displayed, the regulator will
      return to basic display mode.     Figure 18 - LED display indicating error/advisory codes.

XII. ALTERNATOR AND REGULATOR TROUBLESHOOTING
Determining the causes of failures in an electrical system is a "step by step" process. We recommend that you inspect
and clean all system electrical connections before you begin your search to determine if the failure can be attributed to
one of the two main components of your charging system: the alternator, and/or the voltage regulator.
Most charging system problems will be corrected by performing the following steps.
1.    Remove and clean all charging system electrical connections from the alternator through the batteries (this
      includes the ground side). Also, check the voltage regulator's harness for resistance. Wires and terminals can and
      will become corroded and need to be cleaned or replaced.
2.    Charge all batteries to their proper fully charged state and determine if they are serviceable. If your batteries are
      flooded-type, use your hydrometer to determine their condition.
3.    Check and tighten alternator belt. If the belt shows signs of wear or damage, now is an ideal time for replace-
      ment. Always replace existing belts with the finest quality replacements available.
After determining that your batteries and wiring are in suitable condition, use the following tests to determine if charg-
ing problems are a result of a faulty alternator or regulator. The following tests provide an opportunity to isolate the
alternator, regulator and wiring harness in order to determine which component may be malfunctioning. In order to
preform these tests, you will need an independent multimeter (preferably a digital type). In an emergency, a 12V light
bulb can be used to help determine if power or working grounds exist. An amp meter and a battery hydrometer with a
thermometer are also helpful diagnostic tools.
ALTERNATOR /REGULATOR FIELD TESTS
Test A - The alternator and regulator can be tested for function by determining if a magnetic field exists at the alterna-
tor's pulley shaft or rear bearing. To test:
1.    With the ignition in the OFF position, place the head of a steel screwdriver near the nut on the pulley shaft or
      near the rear bearing of the alternator. There should be no evidence of a magnetic field pulling the screwdriver
      toward the alternator.
2.    Engage the ignition, without starting the engine, to activate the voltage regulator. If an oil pressure switch is
      used, a jumper across the switch will activate the regulator.
3.    After allowing time for the regulator's start-up delay, place the head of a steel screwdriver near the nut on the
      pulley shaft or near the rear bearing of the alternator. There should be evidence of a magnetic field pulling the
      screwdriver toward the alternator. If a magnetic field is present, the voltage regulator, alternator brushes and
      rotor are likely to be working properly. If the system is not charging,
      remove the alternator and have it inspected by a qualified alternator
      shop.
Test B - If there is little or no magnetic pull at the pulley shaft or at the rear
bearing, initiate the following test:
1.    With the key off and the engine off, remove the large harness plug
      from the regulator.
2.    Insert the end of a short length of electrical wire to the RED connec-
      tor slot of the regulator harness and the other end of the wire to the
      BLUE connector slot. See figure at right. This bypasses the regulator
      and tests the alternator and the harness.
3.    Using your steel screwdriver, inspect for a magnetic field as described
      above.
                                                                                     B                              R
4.    With your voltmeter, check for voltage on the blue wire at the alterna-
      tor. If voltage does not exist, the harness may be at fault. If voltage
      does exist at the harness, but charging is not occurring, the alternator is likely to be malfunctioning.
If a magnetic field is present. Both harness and alternator brushes and rotor appear to be working properly. If no mag-
netic field is present, proceed with the next test.
Test C - Testing the actual output of the alternator is known as "Full Field Testing". This can be accomplished by
jumping a positive 12VDC current to the field terminal at the rear of the alternator. This test eliminates both the regu-
lator and the harness, making it easier to isolate your investigation to the alternator. CAUTION: Ensure that all voltage
sensitive equipment is turned off prior to starting the engine. Voltage is unregulated during this test and could damage
sensitive electronics. DO NOT let the engine run any longer than necessary to detect charging.
                                                             - 10 -
To test the alternator:
1.    Clip a jumper wire to the positive post of the alternator, or on the battery side of the isolator, if an isolator is in
      use. Use a SHIELDED alligator clip for post attachment. Unintentional contact between the alligator clip and
      the alternator case could result in damage to your electrical system.
2.    Disconnect the field/stator plug from the rear of the alternator and attach the other end of the jumper wire to the
      alternator's Field terminal (F). Attach a female spade connector to the field end of the wire for a solid connec-
      tion. CAUTION: Do not allow the wire to contact the case while it is attached to the positive post. The case is
      grounded and severe damage could occur.
3.    The regulator is now bypassed. When the ignition is engaged and the motor is started, the voltage should rise
      and charging current should be present.
4.    The motor should be run long enough to determine that charging voltage is present. Unregulated voltage can rise
      quickly. Do not allow extended unregulated charging to occur without carefully monitoring voltage levels.
If the alternator fails to generate voltage during field testing, a malfunction of the alternator is likely. Contact your local
alternator repair shop or Balmar's technical service staff for recommendations.
VOLTAGE REGULATOR TEST
When you have inspected and repaired any wires and connections, inspected
belts and replace as needed, and after you have determined that your batter-
ies are properly charged, set your voltmeter to 12V and connect the volt-
meter's negative lead to the BLACK ground wire at the regulator. Normally,
connection is accomplished by inserting the negative lead alongside the
ground wire in the regulator harness plug (see Figure 31) and the positive
lead alongside the wire referred to in each specific test. With the voltmeter
securely connected to the regulator's ground, test for voltage at the points
listed below.
1.    With the ignition in the OFF position and your voltmeter's ground
      wire connected to the regulator's ground, check for voltage on the red       Figure 31 - Testing voltage at regulator.
      (sensing), blue (field) and brown (ignition) wires in the regulator plug
      by inserting the positive lead of the voltmeter alongside each wire in the regulator harness plug. The voltmeter
      should read:
                                     Red Wire             Brown Wire            Blue Wire

2.     With the ignition in the ON position (engine not running) and your voltmeter's ground wire connected to the
       regulator's ground, check for voltage on the red (sensing), blue (field) and brown (ignition) wires in the regula-
       tor plug. The voltmeter should read:
                                     Red Wire             Brown Wire            Blue Wire

3.     With the ignition in the ON position (with engine running at 1,400 rpm fast idle) and your voltmeter's ground
       wire connected to the regulator's BLACK wire, check for voltage on the red (sensing), blue (field) and brown
       (ignition) wires in the regulator plug. The voltmeter should read:
                                     Red Wire             Brown Wire            Blue Wire

* 11.5 - 12.8 VDC battery voltage at rest (no charging occurring). If your batteries are isolated and your RED (sensing) wire shows voltages other
than those shown above, make sure that the wire is connected on the "battery" side of the isolator. The RED wire must "see" the battery directly.
** 13.5 - 14.5 VDC battery voltage when charging.




                                                                      - 11 -
If your readings differ substantially from the "Expected Readings" listed in the charts above, the regulator may be mal-
functioning, or there may be a continuity problem. Contact our technical support staff at (360) 435-6100. Keep your
recorded readings in the spaces provided below the "Expected Readings" so you can share them with the technical sup-
port person. If your readings match those listed in the charts, your regulator should be working correctly. Continue
with tests below to determine if your alternator may be the source of charging difficulties.If the preceding tests do not
prove the existence of a failure within the regulator or alternator, we recommend you contact a licensed marine electri-
cian who can test your system for wiring and circuit damage or other system failures that could be responsible for
charging difficulties. If you determine that repair service is necessary for either your alternator or regulator, please
gather the following information before contacting our service technicians.
1.    Model of alternator.
2.    Model of voltage regulator.
3.    Voltage readings on red, brown and blue wire at regulator with engine off, key on.
4.    Voltage readings on red, brown and blue wire at regulator with engine running at a fast ideal 1400 rpm.
