Inspection

NOTE: An analog-type ohmmeter should be used.

Ignition Power Transistor:

1. Connect the negative (-) terminal of the 1.5 V power supply to terminal No. 5 of the ignition power transistor; then check whether there is continuity between terminal No. 5 and terminal No. 12 when terminal No. 6 and the positive (+) terminal are connected and disconnected.

NOTE: Connect the negative (-) probe of the ohmmeter to terminal No. 12.

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