Ignition Switch Test
- Locate ignition switch connector under dash. Using a 12-volt test light or voltmeter, ensure voltage is present on Black/Red wire when ignition switch is turned to RUN or ON position. This will verify proper operation of ignition switch.NOTE: DO NOT disconnect ignition switch connector during this test.
- If there is no voltage at this wire, problem is either ignition switch, circuit between battery and ignition switch, or 25-amp MAIN fusible link.
