introduction toThe output from the generator can be checked withthe machine still erected on the mounting pole byconnecting an ammeter in the circuit The ammeter willie above 5 mph Fig2If there is no reading on the ammeter disconnect theoutput leads from the battery and check the voltage byconnecting a DC voltmeter across the output leads fromthe generator If the measured voltage is over 12

quite normaldue to the high rpm of the turbineCheck that the machine is secured on the towerEnsure that the blades are fitted correctly Refer toCheck blades for damage If any damage is foundreplace
