Coil Repair Kits

You can find your set in our on-line catalogue.

Reference numbers are marked with „N”. 

Example:  SC7004   coil has its repair kitnamed  SC7004N .

Repair Kits’ benefits​:

 low repair cost of your damaged or out-of-order parts of coils

 low cost of regeneration

 easy to use – you can replace your coil insulators easily

How to use:

 make sure that repair kit is dedicated to your coil

 check the data in catalogue and compare parts provided with those in your coil

 remove damaged parts of coil

 check and rate quality of high voltage contacts. Clean them with proper agent, or in case, wipe with a fine-grained sandpaper

 make sure that resilient connection elements in your repair kit will provide electrical connection.
   High voltate connection elements must touch each other so that there is no flashing of the spark causing burn-out

 make sure that all elements are dry and clean. If necessary, clean dirty elements, especially those around the coil connections

 put repair kit parts in place of parts that are damaged and make sure that they fit and are in the right position

The most common causes of ignition coil failure:

 damage around the low voltage connector

 damage around the high voltage connector

 internal coil damage

Starting from the last cause, internal coil damage, it’s obligatory to say that it’s the rarest cause of damage. Wire inside the coil gets damaged very rarely. It is easier to damage brazed or mechanical connections inside the coil. All the coil elements are filled with resin, which protects the coil against internal connections damage. The most common reason for coil malfunction is a damage or dirty, low voltage connector. Vibrations, high temperaturę, changes in temperature range and pollution cause that the relatively small contacts of the electric connection of the coil and the connector of the power supply and control wires to the coil are initially soiled and patined, and often in a further stage of mechanical damage. In this case, it is usually necessary to replace the coil or connector, if the repair attempt to repair these elements is not successful. However, it is important to remember not to change to coil right away, but make an effort to repair the low voltage connector beforehand. When trying to repair, it is the high time to check the high voltage connector with the insulator. Here we go to the problem of high voltage connector damage. Due to high voltage current flow, the coil connector gets covered with a non-conducting coating. In addition, vibrations and high temperatures cause corrosion of the joining metal of contacts and it may cause a significant increase of resistance and can lead to the loss of ability to spark flashing on the spark plug. Another negatively affecting high voltage coils factor are temperature changes caused by the engine heating up and cooling down, when the vehicle is not used. Then, there is a significant expansion and contaction of metal elements, which over time may lose their electrical connections. All the factors described above make the repair kit helpful to maintain a high voltage coil. Not all coil constructions allow to replace connector elements or high voltage insulators, but wherever possible it is worth to check its conditio from time to time. As in the case of ignition leads, ignition system parts should be replaced about each 2, 3 years.
