IGNITION DISTRIBUTOR CHECK

Check performance of the distributor pickup coil and the amplifier unit by employing either of the test methods described below.

OHMMETER METHOD

1. Detach distributor connector body from harness connector, and connect an ohmmeter to the distributor leads.
2. Slowly rotate magnetic pickup assembly through full advance travel and read ohmmeter. If reading is not within 500-700 ohms replace pickup assembly.
3. If the reading is within the 500-700 ohm range, disconnect one ohmmeter lead and connect to ground.
4. If reading is less than infinity, replace magnetic pickup assembly.
5. If reading is infinite, repair or replace the installed amplifier unit.

DISTRIBUTOR SUBSTITUTION METHOD

1. Detach distributor connector body from harness connector and connect a spare distributor to the harness connector.
2. Connect a tachometer between coil positive terminal and the pink wire at the 3-wire connector on the left side of firewall.
3. With the ignition switch "ON," turn distributor shaft by hand and observe tachometer.
4. If tachometer needle deflects, replace magnetic pickup assembly in distributor installed in engine.
5. If there is no needle deflection, replace the installed amplifier unit.
