A battery in a traditional car cannot directly create engine spark. It’s only rated at 12 volts, after all, so it needs a little help boosting the signal to the spark plugs. To make that happen, a car ...

An ignition coil takes voltage from the battery and multiplies it to create a spark at the spark plugs, which in turn ignites the engine. Cars have been using some form of the coil ignition system for ...

Just like spark plugs, ignition coils can wear down and become faulty over time. There are many common signs that an ignition coil is getting bad, but one obvious sign is an engine misfire, typically ...

Ignition coils sit at the center of every gasoline engine’s spark, yet they usually stay invisible until something goes wrong. When a coil starts to fail, the symptoms can look like fuel problems, ...

An average car dies many deaths, but with the right owner, it can always live to drive another day. When something fails, a DIY diagnosis and fix can save money and eliminate the inconveniences of ...

Ignition coils play a crucial role in a vehicle’s ignition system. They serve to convert the battery’s low voltage into the high voltage necessary to fire the spark plugs. If there’s any malfunction ...

A windings road:It all starts with the concepts of inductance and electromagnetism. Inside an ignition coil there are two sets of wire windings (aka coils, that's why it's called a "coil," get it?).

Hinckley Triumph motorcycle owners have been complaining about ignition coil failures. In Triumph Ignition Coil Replacement Part 1 of this two-part series, we described a coil replacement on a Triumph ...

I have had to replace a number of the ignition coils on my VZ Commodore wagon over the last six months. The “check power train” warning alert activates and the car starts running roughly. Six months ...

An ignition coil is a vital component of a vehicle's ignition system. It is responsible for converting the low voltage from the battery into the high voltage needed to produce sparks at the spark ...
