What would cause a new ignition coil to burn up?
The main cause of ignition coil burnout is the insulating material aging. For example, when the ignition coil high voltage can’t output smoothly, the current turbulence in coil will occur, causing the temperature to rise rapidly and accelerate the insulating material aging.
What happens if you have a faulty ignition coil?
As we mentioned with the fuel economy problem, a faulty ignition coil will often lead to unspent fuel entering into the exhaust system. When this fuel comes into contact with the hot metal of the exhaust or catalytic convertor, it can instantly ignite and explode, creating a back-fire – a loud noise that booms out of the back of the car.
How many ignigtion coils should I replace?
Very easy repair! REMEMBER TO USE ELECTRIC GREESE FOR THE CONNECTORS! Stopped at light-check engine light went on and car started to shake. Replaced all 4 coils The dealer knew what the problem was before they even put the car on the computer to be diagnosed because it is such a common problem with this car.
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.
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.
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.

What causes damage to ignition coils?
Coils fail for a variety of reasons including heat, vibration, or issues on the secondary side of the ignition system. Worn secondary ignition components such as spark plugs or wires can cause a coil work harder, require more voltage, and therefore significantly reduce the operating life of the coil.
How do I know if my coil pack is burnt out?
Common Symptoms of a Faulty Coil Pack
- A rough idle.
- An unexplainably louder-than-usual engine.
- A noticeable lack of power.
- A significant drop in RPMs while accelerating for no apparent reason.
- A blinking or intermittently activating check engine light.
- An active gas warning light when the vehicle has plenty of gasoline.
What happens when a ignition coil pack is going bad?
Coil Pack Problems Usually, if a coil pack is bad, there will be a loss of fire or spark in one or more cylinders. This causes what’s commonly referred to as misfiring. Misfiring can cause drag on the crankshaft, and usually results in a very poor performing engine.
How is the ignition coil connected to the spark plug?
Each spark plug in a car has its own ignition coil. The coil is either physically connected to the spark plug with wires or it sits on top of the spark plug without using wires. The spark plug needs about 15,000 to 20,000 volts of electricity in order to form an electric spark that can ignite the fuel.
How can you tell if your ignition coil is working?
Once the engine is cranked, look for blue sparks forming along the spark plug gap. If you see blue sparks then your ignition coil is working properly. If you don’t see the sparks or if you see orange sparks then this is a sign of the ignition coil malfunctioning.
How much does it cost to replace an ignition coil?
If you have the replacement professionally done then the labor costs will be between $50 and $100 per hour. Therefore, you can expect to pay at least $150 to $200 if you were to take your car to an automotive repair shop and have them replace your ignition coil for you. If you choose to go to a dealership, expect to pay even more.
