What would cause a ignition coil to melt?
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 excessive voltage creates a high amount of heat which consequently melts the coil’s wire insulation.

The car will inject more fuel to compensate for the lack of power, thereby reducing fuel efficiency. Should the Spark Plugs be Replaced with Ignition Coil?
What causes a spark plug to melt an ignition coil?
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. This excessive voltage creates a high amount of heat which consequently melts the coil’s wire insulation.
Can a blow out spark plug be repaired?
Summary: Ford spark plug blowout repair is covered in this article primarily for the Triton 4.6, 5.4 & 6.8 liter SOHC (Single Over Head) engines. If you have a different application, no problem, for a wider coverage of spark plug thread repairs see our Time-Sert thread repair kit section.
