What causes an ignition coil to burn out?
This constant wear on the coil wires eventually can cause them to fail. Over time, the heat can act on the weakened coils and burn them out or melt them and cause them to cross, which also leads to burnout. The two circuits in the ignition coil also generate a lot of heat.
What is the voltage of the ignition coil?
The ignition control module then reduces the voltage to the ignition coil (s) as the charging system comes on line, allowing the voltage to reach as high as 14.5 volts.
Why does my spark plug keep burning out?
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.
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!
Why does my ignition coil keep burning 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.

How does an ignition coil work in a car?
Ignition Coil The ignition coil is a durable electrical transformer that contains the primary and secondary winding circuits (coils) of the ignition system. Ignition coils have an almost-constant voltage running through them as long as the engine is running. The two circuits in the ignition coil also generate a lot of heat.
