DESCRIPTION
General
The electrical system is 24-volt operation with 24-volt
starting, consisting of an alternator and two lead-acid
batteries. The system is the single wire ground return type,
using the machine's structure as ground
Alternator
The alternator is mounted on the engine and is belt driven. It
is a 70 ampere alternator with an integral transformer -
rectifier unit. 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
current to recharge the batteries and maintains them at a full
state of charge.
Batteries
The batteries (1) (Figure 3-1) are located in a box on the left
side of the crane. The batteries are the maintenance free
type and 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
