Attention! The high-voltage part of the ignition system operates at a voltage of more than 1 kV, therefore, in order to avoid injury from an electric discharge, it is forbidden to remove the high-voltage wires from the spark plugs while the engine is running.
1. Using an ohmmeter, we check the resistance between the terminals of the primary winding of the ignition coil. The nominal resistance of the primary winding should be within 2-4 ohms.

2. Using an ohmmeter, we check the resistance of the secondary winding of the ignition coil between the tips of the high voltage wires. The nominal resistance of the secondary winding with wires should be in the range of 23-27 kOhm.

3. Using an ohmmeter, we check the resistance between the tips of the high voltage wires. The nominal resistance of high-voltage wires should be within 6-12 kOhm.

You should also visually check the condition of the conductor on the cut of the high-voltage wire on the side that is installed in the ignition coil. If the conductor is destroyed or burned, it is possible to cut the wire with a sharp knife by no more than 3-4 mm. The same can be done if the tip of the high-voltage wire is removable.
