Wiring Harness
- Disconnect wiring harness connector from ignition module. Inspect connector for dirt, corrosion, or damage. Repair if necessary. Disconnect wire at "S" terminal of starter solenoid.
- Attach negative voltmeter lead to distributor base. Measure voltage at battery. With negative lead of voltmeter still connected to distributor base, check voltages at TFI ignition module wiring harness terminals. See WIRING HARNESS CHECK table. See Fig 1.
- If all readings are at least 90% of battery voltage, wiring harness is okay. Turn ignition off. Remove voltmeter. Connect "S" terminal to starter solenoid. Proceed to appropriate STATOR test.
- If any 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.
