DC GENERATION

DESCRIPTION OF ALTERNATOR SYSTEM
On engines without air conditioning, the alternator is located on front lower right side; front lower left side
with air conditioning. It uses a belt drive from engine crankshaft. Full electrical power output is available
regardless of engine rpm.
The alternator system does not require a reverse current relay, because of high back resistance of diodes
and inability of alternator to draw current or motorize. Therefore a voltage regulator is the only control needed.
The circuit breaker panel contains a 5 ampere circuit breaker marked ALT FIELD. If the field circuit
breaker trips it will result in a complete shutdown of power from the generating system. After a one or two
minute cool-down period, the breaker can be reset manually. If tripping recurs and holding the breaker down
will not prevent continual tripping, then a short exists in the alternator field.
