This ignition switch controls the electrical power flow in the host vehicle. It has positions P, 0, 1, 2, and 3, which correspond to off, accessory, ignition-on, and two start or auxiliary circuits. The switch routes battery voltage to the starter solenoid, the instrument panel, and the loaders electrical system. A worn switch can cause intermittent power loss or a no-crank condition. The six-pin connector matches the original wiring harness layout, so no adapter or rewiring is needed for installation.
