Ignitor Input Test (Legend)
- Turn ignition off. Disconnect wiring harness from ignitor. Using ohmmeter, check for continuity between Black wires and ground. If continuity does not exist, check for open wire or bad ground connection.
- Turn ignition on. Using voltmeter, check for battery voltage between ground and each White wire of harness (including White wires with tracer color). See Fig 1
. If voltage is not present, check for blown fuse No. 25 or open circuit. If circuit and fuse are okay, replace ignition coil.
