Description

Batteries

Provide power for the electrical circuits. Two 12 volt batteries are connected in series to

provide starting power.

The 24 volt, 70 amp alternator, an integral part of the charging circuit, provides current

to charge the batteries when the engine is running.

Starter Motor

Part of the starting circuit, the starter motor is used to turn the engine flywheel fast

enough to start the engine.

Circuit Breakers

Located inside instrument panel. Switches that open the battery circuit if there is a

shorted, grounded wire or excessive current draw by a defective component in the

corresponding circuit. When the circuit is open, no current will flow through the

electrical system. Circuit breakers will automatically reset once they cool. If a breaker

continually trips, the electrical system requires repair.
