Ignition Control Module: Testing and Inspection

NOTE: An analog-type circuit tester should be used.

Ignition Power Transistor Check:

Ignition Power Transistor Check - Chart:

No. 1 - No. 4 coil side
1. Connect the negative (-) terminal of the 1.5 V power supply to terminal (3) of the ignition power transistor and then check whether there is continuity between terminal (8) and terminal (3) when terminal (7) and the positive (+) terminal are connected and disconnected.

NOTE: Connect the (-) probe of the circuit tester to terminal (13).

2. Replace the ignition power transistor if there is a malfunction.
