Ignition system has many different parts so if there are any different problems with engine you need to inspect this system. I advise inspecting the ignition system whenever you make under-bonnet check.
There are many wires and tow-connections in ignition system, which can be corrode, also you can see damaged insulations. Any kinks, breaks or cracks should be repaired.
- Check the plug leads and plugs. Keep the leads clean, dry and free from cracks or kinks.
- Use the special guide clips for the leads to avoid damage from hot surfaces and prevent entanglement of them.
- Use a soft cloth to clean the leads. Notice the high-tension leads should be replaced every two or three years.
- Such easy works of maintenance provide the peak performance of your ignition system. Then check the plug leads fixing and check how the leads are properly connected to the distributor. Follow the contacts. The contacts should be free from wear or damage.
- There is special gap between tip and contacts that must not change.
- If the rotor-arm tip and other details are dirty, lift off the arm and clean it.
- Scrape the corrosion from the contacts if it is.
- See at the coil. The coil has a thick HT lead coming out of the end and two smaller LT leads are around. Check the reliable fixing of these leads. Be sure that the ignition coil is fixed firmly in its mountings.
After this inspection start the engine and look if there is a leakege of high-tension. In this case, you can see blue sparks that said about damaged or wet insulation.
