Can bad ignition coil cause overheating?
Damaged or worn spark plugs As spark plugs wear down, the gap in which each spark plug is fired is widened, meaning the coil needs to provide a higher voltage in order to bridge the gap. This additional strain on the ignition coil may cause voltage overload, leading to overheating and eventually failure.
Why does my ignition coil keep getting replaced?
Frequent replacement of ignition coil may be due to bad spark plug ignition cable or not using the right size of a spark plug. With a bad spark plug ignition cable, there is an increased resistance which can cause the ignition coil to get damaged speedily.
Why does a bad spark plug melt a coil?
This high resistance causes a very high amount of voltage to be generated from your ignition coil’s secondary winding. This excessive voltage creates a high amount of heat which consequently melts the coil’s wire insulation. In our example below the bad spark plug ignition cable has a resistance reading of 5 mega ohms. That’s 5,000,000 ohms!
What should I do if my ignition coil is hot?
The recommended procedure is to turn on the ignition and allow the coil to heat for about 5 minutes or so. This moderately softens the tar inside and the wires can be pulled out. New wires are then inserted along with a new wire seal, which is held in placed by threaded packing nuts.
What causes a 9V ignition coil to overheat?
Had this a long time ago when some car ignition systems (Alpine, Solara, Horizon) which had ballast resistors in the supply to give 9v (which were bypassed for starting with 12v) – when a 9v coil was used in the wrong system it would overheat. Correct, if the 9V coil is fed with 12V.
Why does my ignition coil keep going out?
Here is why! The leading cause of premature failure of an ignition coil is due to a worn or bad spark plug ignition cable. A bad spark plug ignition cable will have a much higher than normal resistance. This high resistance causes a very high amount of voltage to be generated from your ignition coil’s secondary winding.
Do you need to replace Ignition coils with spark plugs?

The recommended procedure is to turn on the ignition and allow the coil to heat for about 5 minutes or so. This moderately softens the tar inside and the wires can be pulled out. New wires are then inserted along with a new wire seal, which is held in placed by threaded packing nuts.
How much does it cost to replace Ignition coils?
Firstly, ignition coil replacement will cost you in-between $264 to $376 that depends on the compatibility of your car. Secondly, it’s your choice to take it to a mechanic or not. Well, I opinion if you have experience and knowledge with regards to this field then you can fix it alone at home. However, if not then consult a mechanic.
