Removal and installation
1. Remove the fuse for the ignition system.
2. Remove the center cover.
3. Disconnect the ignition wires from the ignition coils and disconnect the high voltage spark plug wires.
Note: When disconnecting the high voltage spark plug wire, only hold on to the rubber cap on the wire. If the spark plug wire is disconnected by pulling on the wire itself, internal breaks in the wire circuit may result.
4. Remove coils.
5. Installation is carried out in the reverse order of removal.
Examination
1. Measurement of the resistance of the primary winding of the ignition coil.
- A) Connect the wire from the negative terminal of the 3V power supply to the terminal "2" ignition coils. Then check the condition of the circuit between the pins "3" And "2" ignition coils with disconnected and connected from output "1" ignition coil wire to the positive terminal of the power supply.
Table. Checking the primary winding of the ignition coil.
Conclusion "1" and the positive terminal of the power supply | Circuit between pins "3" And "2" |
connected | Circuit closed (resistance approx. 0.86 ohm) |
not connected | Circuit open |
- b) Replace the power transistor if it is defective.
2. Measurement of the resistance of the secondary winding of the ignition coil.
Measure the resistance between the high voltage terminal and the spark plug wire terminal of the ignition coil.
- Rated value: approx. 12.1 kΩ
3. Checking the ignition system malfunction sensor.
Note: An analog multimeter should be used for testing.
- A) Check resistance between terminals "1" And "2" sensor connector.
- Rated value: 0.1 ohm or less
- b) If the measured value is greater than the allowable value, then replace the sensor assembly.
