TM 9-2320-366-10-1 1-18. ELECTRICAL SYSTEM Figure 1-23. Electrical System The vehicle Electrical System is a combined 12/24 vdc system. Four 12-volt batteries (1, Figure 1-23) are connected in series-parallel with the negative terminal grounded to the vehicle chassis. (1) Positioning the master power switch (2) to on applies power to all electrical circuits needed to operate the vehicle. (2) The starting motor (3) operates directly from the 24 vdc source through the starter pushbutton (4). (3) A 12/24-volt belt-driven alternator (5) 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 gages, windshield wipers/washer, and the Material Handling Crane (MHC). The 12 vdc source supplies electrical power to the vehicle lights and instrument panel lights. (4) The radiator fan off switch (6) is used to keep the radiator fan from engaging. The fan off indicator (7) will illuminate on the lighted indicator display (8) when the radiator fan off switch is disabled. Change 1 1-59
