If you have a classic, vintage, or otherwise old car, you've probably heard of the distributor that it features. It's part of the ignition system that transfers current from the battery to the ...

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 ...

The distributor has two jobs: to house a switch that tells the coil when to send a spark, and to send that spark to each individual cylinder in the correct order. The distributor shaft is spun by the ...

My 1978 Corvette is cutting out under acceleration. I took the car to the dealership, and they told me the distributor was defective and would need to be replaced. I would like to keep as many ...

It seems like such a small thing—that tiny area approximately 0.040 of an inch wide inside each combustion chamber. That area we're talking about is the gap between the electrode and strap on each ...

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 ...

The demands for better emissions and fuel economy in the mid 1970s necessitated leaner fuel mixtures. These leaner mixtures required greater voltage and more spark to ignite. This challenge led GM ...

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 ...

When General Motors introduced the High Energy Ignition (HEI) distributor in the mid-1970s, it was revolutionary. So much so that it still has a strong following among today's hot rodders. Like other ...
