The electrical system is designed to sense pressures and temperatures, activate panel indicators, and generate and store
electrical energy.
The components and their functions are:
Batteries (1) store a supply of 24 V dc power.
Generator (2) supplies 24 V dc power for the system.
Regulator (3) controls voltage output of the generator.
Starter (4) cranks the engine.
Master switch panel (5) connects electrical power from batteries to the system. Panel is main junction point for the main
harnesses and circuit breakers. Heaters and radios are wired direct to batteries.
Instrument panel (6) contains gauges and switches necessary to control carrier.
Warning light panel (7) indicates overheating or low oil pressure in major components of power plant.
Wiring harnesses (8) distribute power to engine, transmission, differential, and other components.
Headlights (9) are used for night vision.
Blackout marker lights (10) and blackout headlight (11) are used for driving in blackout conditions.
