Wiring Harness Shorts Check
- Inspect wiring harness for overheated, burned or bare wires, connecting to control module red, white and green wires or to primary ("BATT" and "TACH") terminals of ignition coil connector.
- Check control module and ignition coil connectors for dirt, corrosion or damage. Connect one lead of ohmmeter to engine ground and other lead to terminals in 4-wire harness connector that mate with orange and then purple module wires.
- Check resistance between the sets of wires in the harness connectors that mate with red and white wires, red and green wires, red and orange wires, red and purple wires, white and green wires, white and orange wires, and white and purple wires. Remove ohmmeter and reconnect all connectors.
- If more than 70, 000 ohms, proceed to "Distributor Stator Assembly Check ". If less than 70, 000 ohms, service or replace defective wires.
