Thorough Check
- Remove high tension cable from distributor cap, and ground it. Be sure control unit harness connector is attached to control unit. See Fig 1.
- Pull back rubber boot on connector. Attach voltmeter positive lead to connector terminal 6, and negative lead to terminal 3. Be sure connector is securely plugged into control unit.
Harness must be connected to Hall control unit.
- Turn ignition switch "ON". Turn engine over by hand, and check voltage reading. It should be 0-2 volts. Turn ignition "OFF". If not to specifications, replace Hall generator unit in distributor or replace distributor.
- If Hall generator met specifications, replace ignition coil. If you think coil may be faulty, check its primary and secondary resistance.
