The ignition coils in your car provide the high voltage electrical current that allows your spark plug to create its spark. These parts are humble looking, and they make use of relatively simple ...

Ignition issues can be a real pain to both diagnose and deal with. Sure, generally speaking, having a faulty ignition coil is a better problem to have than a worn-out turbo or clogged DPF, but ...

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 ...

I have a 1954 Ford with a 272 Y-block. Before I got it the previous owner had added triple carbs, dual pipes, and a PerTronix point replacement kit. The coil was a standard 12V replacement and there ...

Ed Smith demonstrates a quick way to diagnose an ignition coil, focusing on a simple three-second check. #IgnitionCoil #EngineTech #EdSmith ...

Around 1975, General Motors made a significant advancement in stock passenger ignition technology: the High Energy Ignition (HEI). One of its major features was installation simplicity. The coil was ...

At one time or another, we have all been stymied by a gas engine with either a no-start or a hard-start condition, or another performance issue that seems to elude logic. The engine has fuel, spark, ...

High-voltage experimenters have been using automotive ignition coils to generate impressive sparks in the home lab for decades, and why not? They’re cheap, easily obtainable, and at the end of the day ...

The ignition coil converts the vehicle’s 12 volts to the more than 10,000 volts required to produce an effective spark in the spark plugs, which in turn ignite the air-fuel mixture in an engine’s ...
