Generating System Operation.
The generating system is identical for all vehicles covered in this manual and consists of the following major
components and circuitry:
F
VOLTMETER - Indicates electrical system voltage. It is connected to the electrical system through circuit 27.
G
ALTERNATOR - Rated at 26-30 volts, 60 amperes, the alternator assists and recharges the batteries during
operation. A 100 ampere model is available as a kit.
H
CIRCUIT 3 - Provides a ground circuit to the alternator.
I
CIRCUIT 566 - Controls a relay in the protective control box that prevents the starter from reactivating while
the engine is running.
J
CIRCUIT 568 - Senses system voltage and excites the alternator field.
K
PROTECTIVE CONTROL BOX - Connects circuit 5 to 81 to power the electrical system and charge the
batteries.
L
CIRCUIT 5 - Conducts alternator output to charge the batteries and maintain vehicle voltage.
M
BATTERY SWITCH - Closes the relay in the protective control box that connects battery circuits.
