The generator output should reach or exceed 20 amperes. Stop the engine and disconnect the jumper wire from the field and armature terminals as soon as the generator output is observed to prevent overheating of the generator. If the generator output is below 20 amperes or ammeter readings are observed to be erratic, check the generator belt tension and adjust as necessary. To adjust the generator belt tension, loosen the two generator pivot bolts located at the base of the generator. Loosen the belt tension adjusting bolt nut.
Proper adjustment is important.
An over tightened belt may cause premature wear of the generator armature shaft bearings. A loose belt may result in belt slippage, poor generator performance, and an overheated engine. If adjusting the belt does not increase the output of the generator to 20 amperes or more, remove and repair or replace the generator. Bare wiring must be repaired or replaced. The generator output test, outlined above, must be performed to ensure the proper performance of the generator.
