Ignitor Input Test
- Turn ignition off. Unplug wiring harness from igniter. Test for continuity between Black wires and ground. If continuity does not exist, inspect for open wire or bad ground connection.
- Turn ignition on. Test for battery voltage between ground and each White wire of harness (including White wires with tracer color). See Fig 1. If battery voltage does not exist, inspect for blow n fuse No. 25 or open circuit in White wire. If circuits and fuse are okay, replace ignition coil.
