Manual Instruction Extract

Electrical Supply System: The electric power circuit provides current to each component, consisting of the battery, starter switch, fusible link, and fuse box. The negative terminal of the battery is grounded. Current is supplied even in the “OFF” switch position to essential components including the cabin light and fuel pump switch. During “ON” or “START”, power flows from the battery through the fusible link to energize the electric supply system. The battery powers components when the engine is off, and the alternator takes over once the engine is running.
