Ignition Leads

Spark plugs and ignition coil are connected to ignition cable. In the ignition coil voltage reaches 30,000 volts, so the spark plug wire is situated in an inaccessible place for people. Security must be respected under all conditions. Ignition cable must withstand big temperature spans and mechanical loads. All this is confirmed by the ISO certificate. 

A very important point is the elimination of radio interference, which the voltage in the ignition system depends on. What system to use depends on the car brand. When choosing spare part, pay attention to the manufacturer technical characteristics. In the worst case faulty ignition cable may result in damage, in the best case it will malfunction. The easiest way out is to replace the original cable for a particular car model. However, the replacement is possible only if the ignition cable consists of separate parts. Car owner won’t be able to replace the ignition cable, as he needs special pliers to connect terminals to the ends of the cable.

If the problem is with ignition cable, it is possible to identify by voltage measurement. All this must do specialists. To replace the ignition cable you also need a special voltmeter. It is not difficult to replace the cable with a new one. Do you need McPherson strut, turn indicator, brake pads or brake shoes, timing belt, brake force regulator, tie rod, gear wheel or other spare part? In our web shop you will find any spare part you need.

HOW TO DETECT MALFUNCTION OF THE IGNITION WIRES

Checking the component, start with visual inspection. Check wires' insulation (with ignition off). The joints and bends of the wires should not have any damage (cracks, scorch marks or holes).

Next, make sure there is no rust between the ignition coil and the wire terminals.

If no damage has been found, determine the degree of resistance. To do so, use a multimeter. Connect probes of the measuring device to both ends of the wire. The normal resistance is 3.5 to 10 kOhm. If the difference of wires' resistance within the same set exceeds 4 kOhm, the wires are to be replaced.

Next check the operation of the ignition wires with the engine started. Be careful as the ignition wires are under high voltage. If clicking sounds produced by electric current are heard, or there are sparks, the ignition wires are to be replaced. Ignition wires should be diagnosed no less than once in 3 months.
