Wiring Harness
- Disconnect wiring harness connector from ignition module. Inspect connector for dirt, corrosion or damage. Disconnect wire at "S" terminal of starter solenoid.
- Attach negative voltmeter lead to distributor base. Measure battery voltage. With negative lead of voltmeter still connected to distributor base, check voltages at TFI-IV ignition module wiring harness terminals. See Fig 1. See WIRING HARNESS TEST table.WIRING HARNESS TEST
Connector Terminal No. Wire (Circuit) Ignition Switch Test Position 2 Coil-Terminal "RUN" 3 Run "RUN" or "START" 4 Start "Start" - If all readings are at least 90% of battery voltage, wiring harness and connectors are okay. Go to STATOR test. If reading is less than 90% of battery voltage, inspect wiring harness and connectors. Also check for a worn or damaged ignition switch. Repair or replace as necessary. Turn ignition off. Remove voltmeter. Connect "S" terminal to starter solenoid.
