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 ...

The discrete ignition coil in older 12V vehicles is an amazing little pulse transformer that multiplies low voltage received from the battery or alternator to many thousands of volts when the breaker ...

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 ...

High energy ignition systems use a transistorized switch within an ignition module that also handles the task of triggering the ignition coil to generate high-voltage current. This is advantageous, as ...

"It's not a heap, dad. It's a classic." That's harder to justify when your classic muscle car won't start. Nothing like a high-compression V8 combined with a battery that hasn't seen a charge for a ...
