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; 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.
