How does an ignition system with points work?

When the ignition key is turned on, a low voltage current from the battery flows through the primary windings of the ignition coil, through the breaker points and back to the battery. As the engine rotates, the distributor shaft cam turns until the high point on the cam causes the breaker points to separate suddenly.

What is a points style ignition system?

Ignition points are a set of electrical contacts that switch the coil on and off at the proper time. The points are opened and closed by the mechanical action of the distributor shaft lobes pushing on them. The points have a tough job, switching up to eight amps of current many times per second at highway speed.

How do you convert points to electronic ignition?

There are two ways you can go about converting from points to electronic ignition – you can install a factory electronic system that replaces the factory points and distributor, or you can install an aftermarket high-performance system with parts and components from various manufacturers.

How often should you change ignition points?

Depends on what kind of driving you do, and what kind of condition the rest of your electrical system is in, but in general, points need to be set every 6,000 miles or so. With one or two cleanings, a good set of points should last at least 5,000 miles, and possibly as many as 8,000.

What replaced points in a distributor?

The distributor shaft has a cam that operates the contact breaker (also called points). Opening the points causes a high induction voltage in the system’s ignition coil. Around the 1970s the primary breaker points were largely replaced with a Hall effect sensor or optical sensor.

Does electronic ignition add horsepower?

One of the easiest ways to increase the horsepower output of your classic car is by converting from the old, maintenance-intensive, unreliable points/breaker-type ignition to electronic ignition. Points-type ignitions are subject to wear which degrades engine performance and this wear begins immediately.

How can I make my ignition points last longer?

Points will last until the rubbing block wears out if you have electronic ignition. Put on a dab of points grease the size of a match head each time you service them and they will last a long long time.

What are 2 classifications of ignition systems?

Ignition systems can be divided into two classifications: magneto-ignition systems or electronic Full Authority Digital Engine Control (FADEC) systems for reciprocating engines. Ignition systems can also be subclassified as either single or dual magneto-ignition systems.
