Ignition Control Module: Testing and Inspection
NOTE: An analog-type ammeter should be used.
Power transistor for coil No.1(2) and No.4(3) cylinders.
1. Connect the negative (-) terminal of the 1.5 Volt power supply to terminal 4 of the power transistor; then check whether there is continuity between terminal 1(6) and terminal 4 when terminal 2(7)and the positive (+) terminal are connected and disconnected.
NOTE: Connect the negative(-) probe of the ammeter to terminal No.4.
2. Replace the power transistor if there is a malfunction.
