Primary Circuit Continuity Check
- Carefully insert a small straight pin in Green ignition module wire. Connect negative voltmeter lead to engine ground and positive voltmeter lead to pin in Green wire.
- Turn ignition switch to "RUN" position, and measure voltage. Turn ignition switch "OFF", remove voltmeter and straight pin.
- If voltage was greater than 1.5 volts, proceed to "Ground Circuit Continuity Check". If voltage was 1.5 volts or less, proceed to "Ballast Resistor Check".
