Heat pump not performing? Before swapping parts, here’s how to use simple techniques — like the touch test — to confirm a ...

An ignition coil is a crucial component of a vehicle’s ignition system, responsible for converting the battery’s low voltage into the high voltage needed to ignite the fuel-air mixture in the engine.

Abstract: Solenoid-type superconducting magnetic energy storage (SMES) coils wound by Bi-2223 tapes have strong anisotropic magnetic field dependence due to the fundamental anisotropic property ...

In this video, I’ll show you exactly how to test your BMW spark plugs, ignition coils, and coil wiring without needing a multimeter—just using the kit provided. Whether it’s a misfire, bad coil packs, ...

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 ...

The reality is that like almost every component under the hood, a car battery has a finite lifespan and will conk out on you eventually. Weather conditions, corrosion, electrical shorts, charging ...

While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...
