Inspection
Ignition Power Transistor: No.1 - No.4 Coil Side:
[1][2]IGNITION POWER TRANSISTOR
NOTE:
An analog-type circuit tester should be used.
No.1 - No.4 coil side
1. Connect the negative (-) terminal of the 1.5V power supply to terminal 4 of the [1][2]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 [1][2]ignition power transistor if there is a malfunction.
Ignition Power Transistor: No.2 - No.5 Coil Side:
No.2 - No.5 coil side
1. Connect the negative (-) terminal of the 1 .5V power supply to terminal 4 of the [1][2]ignition power transistor; 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.

Coil C (No.3 - No.6 cylinder side coil) 4 - 3
Standard value: 0.67 - 0.81 Ohms
Secondary Coil Resistance:
Secondary Coil Resistance
Measure the resistance between each coil high voltage terminals.
Measuring point:
Coil A (No.1 - No. 4 cylinder side coil)
Coil B (No.2 - No. 5 cylinder side coil)
Coil C (No.3 - No. 6 cylinder side coil)
Standard value: 11.3 - 15.3 k-Ohms
