ELECTRICAL SYSTEM
Alternator, Battery, and Starting Systems (Vehicle S/N 11,438 to 18,549). The
vehicle Electrical System is a combined 12/24 VDC system. Four 12-volt batteries are
connected in series-parallel with the negative terminal grounded to the vehicle chassis.
1.
Positioning the master power switch to on applies power to all electrical circuits
needed to operate the vehicle.
2.
The starting motor operates directly from the 24 VDC source through the starter
pushbutton.
3.
A 12/24-volt, belt-driven alternator with a 100-amp capacity maintains the charge on
the batteries. The 24 VDC source supplies electrical power to operate the starting
motor, Central Tire Inflation System (CTIS), fuel/water separator, air dryer, ether
injection system, instrument panel assembly gages, windshield wipers/washer, and
the Material Handling Crane (MHC). The 12 VDC source supplies electrical power to
the vehicle lights and instrument panel assembly lights.
