Why does my ignition coil keep blowing?
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.
Do ignition coils fail often?
If your vehicle’s fuel-to-oxygen mixture is either rich or lean, therefore, your ignition coils may fail prematurely. Additionally, engine heat and vibrations can cause damage to ignition coils. Nevertheless, on most vehicles can go 80,000 to 100,000 miles before requiring an ignition coil replacement.
Why does my car’s ignition coil keep failing?
Ignition coils tend to fail because of bad spark plugs or plug wires. If your vehicle’s fuel-to-oxygen mixture is either rich or lean, therefore, your ignition coils may fail prematurely. Additionally, engine heat and vibrations can cause damage to ignition coils.
When to replace spark plug and ignition coil?
In the event that there is a coil failure due to an excessive gap, the spark plug and ignition coil should be replaced. It is also recommended that the ECU driver is verified for proper operation. Moisture is another cause of ignition coil damage, coming from the most likely and unlikely of places.
Where is the ignition coil located on a car?
Older vehicles have a distributor, ignition coil, and spark plug wires. Most vehicles made after the late 1990s typically have a small ignition coil that sits directly on top of each spark plug, which is known as coil-on-plug (COP) design. Regardless, the functionality is the same. When you start your engine, current flows to the ignition coil.
What should the voltage be on an ignition coil?
Regardless, the functionality is the same. When you start your engine, current flows to the ignition coil. The coil, being a compact electrical transformer, then steps up the voltage level from 12 volts to as high as 60,000.
