The ignition coil must be checked with an ohmmeter in the event that there are no peak voltages on the spark plugs (for ignition sparks), despite the fact that the starter is working.
Disconnect the negative (-) cable from the battery.
Warning! This will erase data in electronic memory devices, such as the engine fault memory device or the radio code. Please read the section carefully "Removing and installing the battery", before disconnecting it.
Examination
Disconnect all ignition wires from the ignition coil by squeezing the locking tabs on each end. To gain access to the ignition coil, you must first remove the air intake hose, see p. 5.6.
Check the resistance of the primary winding: to do this, remove plug "1", while pressing the metal bracket.
The figure shows the ignition coil terminal "1". Connect the ohmmeter to the corresponding ignition coil terminals and check the resistance between the following terminals in sequence:
- between contacts 1 and 2.
- between contacts 3 and 2.
The specified value for two measurements (resistance of the primary winding of individual ignition coils) is 4.5-5.5 Ohm.
If significant deviations from the specified value are detected, replace the ignition coil.
Replacing the ignition coil
Attention! If it is necessary to replace the ignition coil, it is necessary to remember that under no circumstances should an ignition coil designed for an ignition system with a breaker be installed.
Unscrew the mounting bolts and remove the ignition coil.
Screw on the new ignition coil, connect the side plug.
Connect the ignition wires to the ignition coil, making sure the locking tabs snap into place.
Attention! The high-voltage wire sockets are marked with numbers from "1" to "4". Connect the wires in accordance with the ignition sequence 1-3-4-2. Cylinder 1 is located on the V-belt side of the engine (looking in the direction of travel - on the right).
Connect the ground (-) wire to the battery. Set the existing clock and set the radio code.
