The ignition (or distributor) cap is where ignition wires that run to the spark plugs receive high-voltage current from the ignition coil. Metal contacts in the cap connect with contacts in the ...

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 ...

Worn ignition component gremlins are mysterious little buggers. Ignition misfires can be confused with fuel mixture or delivery problems. Even ambient humidity can affect the ignition system—making a ...

For the average beginner in the fine art of auto mechanics, and some old-timers as well, installing and wiring a stock eight-cylinder ignition distributor can sometimes be quite a chore, and when he ...

When you’re trying to learn about older cars, you might as well be signing up for the debate club. Every question, especially when it comes to breaker points, electronic, and multiple spark discharge ...

Automotive ignitions systems have seen many transitions over the years. Historically, the designs have matured from a magneto to today’s coil-over-spark plug designs. The progression follows the ...

Older vehicles with distributor-type ignition systems use ignition (or spark plug) wires to send electrical current from the distributor to individual spark plugs, with the timing based on their ...

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 ...

Q. I've noticed my new car doesn't have a distributor or spark plug wires, unlike every other car or truck I've ever owned. Can you explain how this works? A. This is one of the neatest automotive ...
