Component Inspection

IGNITION COIL CHECK




Primary Coil Resistance
Measure the resistance between connector terminal 3 (power) and each coil terminal.
Measuring point:
No.1 - No.4 cylinder side coil; 2-3
No.2 - No.3 cylinder side coil; 1-3
Standard value: 0.70 - 0.86 Ohms




Secondary Coil Resistance
Measure the resistance between coil high voltage terminals Measuring point:
No.1 - No.4 cylinder side coil; A
No.2 - No.3 cylinder side coil; B
Standard value: 11.3 - 15.3 K Ohms

IGNITION POWER TRANSISTOR CHECK

NOTE: An analog-type ohmmeter should be used.

No.1 - No.4 coil side




1. Connect the negative (-) terminal of the 1.5 V power supply to terminal 3 of the ignition power transistor; then check whether there is continuity between terminal 8 and terminal 3 when terminal 7 and the positive (+) terminal are connected and disconnected.





NOTE: Connect the (-) probe of the ohmmeter to terminal 8.

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

No.2 - No.3 coil side




1. Connect the negative (-) terminal of the 1.5 V power supply to terminal 3 of the ignition power transistor; then check whether there is continuity between terminal 1 and terminal 3 when terminal 2 and the positive (+) terminal are connected and disconnected.






NOTE: Connect the (-) probe of the ohmmeter to terminal 1.

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