Component Test

ECU Component Pin-Outs:

1. Disconnect the 6 pin igniter connector.

2. Turn ignition switch on.

3. Using a voltmeter, connect the positive probe to terminal #3 of the harness. Connect the negative probe to body ground.

Voltage: Approximately 12 Volts

4. Reconnect the 6 pin igniter connector.

5. Turn ignition switch off. If voltage was not within specifications, check fusible links, ignition switch, and connections from battery to igniter.

Power Transistor, Coil Connector C:

6. Disconnect the 4 pin igniter connector.

7. Disconnect each ignition coil connector. Turn ignition switch on.

8. Using an ohmmeter, connect terminal #2 of ignition coil connector C and body ground.

9. Using a 3V dry cell battery, apply voltage to terminal #2 of the 4 pin igniter connector. As voltage is applied, ensure there is momentary continuity.

Power Transistor, Coil Connector A:

10. Using an ohmmeter, connect terminal #2 of ignition coil connector A and body ground.

11. Using a 3V dry cell battery, apply voltage to terminal #4 of the 4 pin igniter connector.

12. With terminal #4 connected, apply voltage to terminal #2 of the 4 pin igniter connector. As voltage is applied ensure there is momentary continuity.

Power Transistor, Coil Connector B:

13. Using an ohmmeter, connect terminal #2 of ignition coil connector B and body ground.

14. Using a 3V dry cell battery, apply voltage to terminal #3 of the 4 pin igniter connector.

15. With terminal #3 connected, apply voltage to terminal #2 of the 4 pin igniter connector. As voltage is applied, ensure there is momentary continuity.

16. If continuity did not exist in steps #9, #12, and #15, replace igniter (power transistor) assembly.
