Do ignition coils last forever?
The ignition coil on your car is supposed to last around 100,000 miles or more. There are a number of factors that can lead to this part become damaged prematurely. Most of the newer cars on the market have a hard plastic cover that is designed to protect the coil from damage.
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.
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.
How many volts does an ignition coil need?
The average car uses a 12V battery, and the spark plugs need about 20,000 to 40,000 volts to ignite the fuel. This is the reason the ignition coil is also known as a compact transformer. The ignition coil has two windings wrapped around an iron core.
Why do you need a coil pack ignition?
Nowadays, most modern cars replaced the distributor with a coil pack, thus, increasing electronic transmission efficiency. However, because a coil pack ignition system involves fewer moving parts, identifying ignition coil problems and their correction poses challenges to a car owner.
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 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 many ignition coil failures in 2 weeks?
Less than a week (and not much driving – 50 miles tops) later, on the highway, it starts shuddering again, feels way underpowered, and the check engine flashes. It’s pretty scary. I pull over and have it towed to the mechanic.
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.
