Ignition Control Module: Testing and Inspection

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







No. 1 - No. 4 coil side
1. Connect the negative (-) terminal of the 1.5 V power supply to terminal (4) of the ignition power transistor and then check whether there is continuity between terminal (13) and terminal (4) when terminal (3) 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.







No. 2 - No. 5 coil side
1. Connect the negative (-) terminal of the 1.5 V power supply to terminal (4) of the ignition power transistor, and then check whether there is continuity between terminal (12) and terminal (4) when terminal (2) and the positive (+) terminal are connected and disconnected.

NOTE: Connect the (-) probe of the circuit tester to terminal (12).

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







No. 3 - No. 6 coil side
1. Connect the negative (-) terminal of the 1.5 V power supply to terminal (4) of the ignition power transistor, and then check whether there is continuity between terminal (11) and terminal (4) when terminal (1) and the positive (+) terminal are connected and disconnected.

NOTE: Connect the (-) probe of the circuit tester to terminal (11).

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