2. Disconnect tips from spark plugs. In this case, you need to pull not by the wire, but by the tip.
3. Disconnect the high voltage wires from the ignition coils. Before disconnecting, mark the wires so that you can connect them in the correct sequence later. The order of connecting the wires to the coils is also indicated on the wires themselves, if they are original spare parts.
4. Measure the resistance of the high voltage wires with an ohmmeter. The nominal value of the resistance, depending on the length of the wire, is 3-20 kOhm (see illustration).
3.4 Measure the resistance of the high voltage wires with an ohmmeter. The nominal value of the resistance, depending on the length of the wire, is 3-20 kOhm
If the resistance is too high, clean the wire contacts and repeat the measurement. Replace wires if necessary.
5. Check the condition of the insulation of the high voltage wires by bending the wire near the lug under a small radius. Make sure. That the insulation is not cracked. Otherwise, replace the spark plug wires with new ones.
6. Connect the wire ends to the spark plugs, guided by the markings, in the sequence of cylinders 1-3-4-2. Cylinder #1 is on the flywheel side.
