Ignition coils play a crucial role in a vehicle's ignition system as essential components that facilitate the engine's combustion process. They are responsible for converting the low voltage supplied ...

"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 ...

This ignition coil driver is a HOT one! From my recollection, it delivers a nastier spark than the legendary Ford Model T ignition coil. The circuit uses an inverted 555 oscillator that is coupled to ...

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 ...

Drag racers are constantly searching for ways to either go faster down the quarter-mile or to make those quarter-mile blasts become more consistent. There are plenty of ways to make more horsepower ...

Paging through an ignition catalog reveals all sorts of different ignition coils for conventional distributor-type ignition systems. To say it's a mite confusing is an understatement!Just how does an ...

Corvettes have had electronic ignition systems for over 40 years, starting with the powerful, dependable Delco HEI (high energy ignition) system in 1975 models. Prior to that, nearly all Corvettes, ...

Relays are common electromechanical devices in electrical circuits that come in two types: either latched or non-latched. Latched relays retain their last switch position even after complete power ...

As long as there have been internal combustion engines, there has been a need for an ignition system to ignite the air and fuel mixture in the cylinders. From the earliest days of automotive ignitions ...

Relays and solenoids are available with many different voltage ratings. Most factory- and process-automation equipment operates from 24-V supplies. However, customers may have control signals for a ...

Question: I have a 2006 Kia Sedona, and it randomly misfires roughly once for every week of normal driving and once after each carwash. When it happens, I pull over and shut off the car. Then, I turn ...
