Hinckley Triumph motorcycle owners have been complaining about ignition coil failures since, well, probably since the first Bloor Triumph sputtered off the assembly line. This is Part 1 of this ...

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?).

Every gasoline engine is basically a series of controlled explosions, and the coil pack is the component that lights the fuse. Your car's battery puts out a measly 12 volts, which is great for your ...

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 ...

The ignition coil in C1, C2, and early C3 Corvettes is truly an amazing little device. An ignition coil is a type of pulse transformer that multiplies the low voltage received from the battery or ...

At 7,000 rpm, a spark plug ignites the air/fuel mixture nearly 60 times per second. Any one of those 60 sparks going amiss can at best be mildly annoying, and at worst cost you a race or an engine.
