7.2. Ignition coil

Check of tension

PERFORMANCE ORDER
1. Disconnect a wire from the negative plug of the rechargeable battery.
2. Disconnect the socket from the ignition coil.
3. Turn a key in the ignition lock in the provision of "ON".
4. Measure tension between blue and green wires in the ignition coil socket.

Tension: 12 V

5. In the absence of tension, check serviceability of a safety lock, the lock of ignition and a plait of wires.

Check of resistance

PERFORMANCE ORDER
1. An ohmmeter check resistance of primary winding of the coil of ignition. Connect one probe of an ohmmeter to positive (+) to a clip and other probe to each negative clip. If resistance differs from demanded, replace the ignition coil. Remember that the block contains two coils which resistance needs to be checked.

Resistance of primary winding: 0.45–0.55 Ohm at 20 °C

2. An ohmmeter check resistance of a secondary winding of the coil of ignition. If resistance differs from demanded, replace the ignition coil.

Resistance of a secondary winding: 13–15 kOhm at 20 °C

Removal

PERFORMANCE ORDER
1. Disconnect a wire from the negative plug of the rechargeable battery.
2. Disconnect high-voltage wires.
3. Disconnect sockets from the ignition coil.
4. Turn out four bolts of fastening of the coil of ignition.
5. Remove ignition coils.

Installation

PERFORMANCE ORDER
1. Install two coils of ignition over spark plugs 2 and 4 of cylinders and press them for connection.
2. Screw four bolts of fastening of the coil of ignition.

Inhaling moment: 19–25 N • m
3. Connect sockets to the ignition coil.
4. Connect high-voltage wires.
5. Connect a wire to the negative plug of the rechargeable battery.
