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 ...

Mechanic holding an ignition coil while working on an engine - Михаил Руденко/Getty Images Ignition issues can be a real pain to both diagnose and deal with. Sure, generally speaking, having a faulty ...

Over the past few years, we have run across some teams who, for the goal of attaining maximum power, chose to run without an alternator. We started thinking about that and decided to see if there were ...

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?).

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 ...
