DESCRIPTION
General
The electrical system is 24-volt operation with 24-volt
starting, consisting of an alternator and four 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
detailed information on the electrical swivel, refer to Swivels,
page 6-16.
The carrier control module locations are shown in (Figure 3-
1) and listed in (Table 3-1).

Alternator
A 150 ampere alternator is mounted on the engine and is belt
driven. When the engine is running, and the alternator is
turning, the alternator's 24-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.
Batteries
The batteries are located in a box on the left front side of the
crane. The batteries are the maintenance free type and are
completely sealed except for a small vent hole in the side.
The vent hole allows what small amount of gases that are
produced in the battery to escape. On some batteries, a test
indicator located on the top of the battery is used to
determine if the battery can be tested in case of a starting
problem.
In addition to the batteries, the battery box also contains a
manual battery disconnect switch, a power relay, (2) fuse
and relay modules, (3) 100A fuses, (1) 250A fuse and (1)
