DESCRIPTION

General
The electrical system is 12-volt negative ground with 12-volt
starting, consisting of an alternator and three 12-volt lead-
acid batteries. The system is the single wire ground return
type, using the machine's structure as ground.
Electrical power is transferred to and from the carrier and
superstructure through the electrical swivel. For more

Refer to the electrical schematic in the back of this manual to
aid in troubleshooting an electrical problem.
Alternator
The alternator (Figure 3-1) is mounted on the engine and is
belt driven. It is a 145 ampere alternator with an integral
transformer - rectifier unit. When the engine is running, and
the alternator is turning, the alternator's 12-volt output
terminal supplies the crane's electrical circuits. The output
terminal also supplies the voltage to recharge the batteries
and maintains them at a full state of charge.
