Primary Circuit Continuity Check
- Insert a small straight pin in control module Green wire. Connect negative voltmeter lead to distributor base and positive lead to pin in Green wire. With ignition switch in "RUN" position, measure voltage. Turn ignition switch "OFF" and remove straight pin from Green wire.
- If voltage reading was greater than 1.5 volts, proceed to "GROUND CIRCUIT CONTINUITY CHECK ". If voltage reading was 1.5 volts or less, replace control module.
