Module Inspection

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

1. Connect the negative (-) terminal of the 1.5V power supply to terminal 5 of the ignition power transistor; then check whether there is continuity between terminal 5 and terminal 12 when terminal 6 and the positive (+) terminal are connected and disconnected.

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

Terminal 6 and (+) terminal Terminal 5 and terminal 12

Connected Continuity
Unconnected No continuity

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