[Teodor] writes in with a unique Tesla coil he designed and built. Unlike most Tesla coils, [Teodor]’s design is able to run with a fairly low input voltage because it doesn’t use a static spark gap ...

This animated film "Spark In The Firing Line" provides an in-depth look at the ignition system of modern motor vehicles, focusing on the role of spark plugs in igniting fuel within the combustion ...

For car enthusiasts and performance seekers, optimizing engine response is a thrilling endeavor. Ignition systems play a ...

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 ...

We're always looking for ways to make more power without spending too much money. We bolt on carburetors and intake manifolds. We also perform cam swaps in our quest for power. When that doesn't meet ...

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 ...

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 ...

"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 ...

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 ...

Pickering Electronics has introduced high-voltage reed relays with a higher coil resistance for low power consumption compared to its existing Series 104 – high-voltage specifications are the same as ...

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, ...
