Measurement of the primary coil resistance
Measure the resistance between connector terminals 1 and 2 (the coils at the No. 3 and No. 6 cylinder sides) of the ignition coil, and between terminals 2 and 4 (the coils at the No. 1 and No. 4 cylinder sides), and between terminals2 and 3 (the coils at the No.2 and No.5 cylinder sides).
Measurement of the secondary coil resistance
Measure the resistance between the high-voltage terminal for the No. 3 and No. 6 cylinders, between the high-voltage terminals for the No. 1 and No. 4 cylinders and between the high-voltage terminals for the No.2 and No.5cylinders.
When measuring the resistance of the secondary coil, be sure to disconnect the connector of the ignition coil.
Measurement of the primary coil resistance
Connect the negative (-) terminal of a 3V power supply to terminal 2 of the power transistor; then check whether there is continuity between terminal 3 and terminal 2 when terminal 1 and the positive (+) terminal are connectedand disconnected.
Terminal 3 and (+) terminal | Terminal 1 and (+) terminal 2 |
Connected | Continuity (Approximately 0.86Ω) |
Disconnected | Non continuity |
Measurement of the secondary coil resistance
Measure the resistance between the high-voltage terminals of the ignition coil.
