If you’ve ever been in an accident, you know that it can be difficult to determine the cause. In some cases, it’s fairly obvious–a tire went flat, for instance. But what about other cases? One of the most common causes of car accidents is ignition coil failure. In fact, it’s responsible for up to 50% of all car accidents. So if you’re having trouble with your car, or you just want to make sure it stays in good condition, it’s important to check your ignition coils. Fortunately, knowing how to test your ignition coils is easy–and we have a guide that walks you through the process step by step. Read on and learn how to test your car’s ignition coils for free!
What is an ignition coil?
An ignition coil is a small device that helps start a engine. It’s located near the spark plug and helps create an electric spark that ignites the fuel in the cylinder. If your ignition coil is bad, it won’t be able to create enough sparks to start your engine. This can cause problems with your car’s electrical system, including decreased fuel economy and difficulty starting the engine.
How do coils work?
Coils work by sending an alternating current through the wire coil. This current causes a magnetic field to form around the coil, which in turn induces a current of electricity in the wire. The voltage that is produced by this current is what powers your engine. When one of your coils starts to wear out, it can cause problems with your ignition system. Here are some signs that indicate you need to replace your coil:
-Your car will not start
-The spark plugs will not fire
-The car has a difficult time starting in cold weather
What are the 5 most common problems with ignition coils?
The five most common problems with ignition coils are as follows:
1. A bad coil will cause your car to not start.
2. A bad coil can also cause your car to run rough or incorrectly.
3. A bad coil can even cause the car to not power up at all.
4. A bad coil can also prevent your car from starting in cold weather conditions.
5. Finally, a bad coil can even lead to a fire in your engine.
How to test an ignition coil
Testing an ignition coil is a relatively simple process that can help determine if it’s bad. To test an ignition coil, first remove the spark plug from the engine. Then, using a voltmeter, measure the voltage at the sparkplug gap. If the voltage is low, the ignition coil may be bad.
Conclusion
Many times, we hear complaints from our customers about the sound of their engine when they start it up. After investigating the issue, many times it is determined that an ignition coil has gone bad. Luckily, replacing this part is relatively easy and can be done in just a few hours by a mechanic with some basic tools. If you think your ignition coil might be the problem, don’t hesitate to bring it in for inspection and replacement.
