- Attach the red lead on your meter to the negative "-" terminal on the ignition coil.
- Attach the black lead on your meter to any good ground on the engine; that is, an unpainted metal part.
- Set the meter for the number of cylinders your engine has. There should be a switch with engine settings on it.
What happens if point gap is too big?
Re: What is the effect of the points gap being too large? Too wide a point gap decreases the dwell angle. This does not give the coil sufficient time to charge, resulting in a weak spark. It also slightly retards the timing.

How does point gap affect timing?
The dwell, as well as spark plug gap, do have an effect on ignition timing. The later the points open, the later the spark comes and retards the timing. The earlier the points open the sooner the spark comes and advances the timing. That is why timing is the last thing to be set in a tune-up.
What should the points gap be?

How do I know if my points are working?
Use a socket and a breaker bar to rotate the engine so that the points are at their widest gap. The gauge, either a wire type or feeler type, should just slide between the points without pushing them apart. If this doesn't solve the problem, try tracing the entire circuit, starting with the battery.
What does a condenser do on a set of points?
The condenser absorbs the energy and prevents arcing between the points each time they open. This condenser also aids in the rapid collapse of the magnetic field.
How can you tell if a point condenser is bad?
A failing points and condenser system can cause rough running, misfires, lean and rich conditions. If the engine is difficult to start, and runs rough once it does start, then it is time to contact a mechanic to have a look at the system and find out exactly what the problem is.

What happens if your spark plugs arent gapped right?
Q: What Happens If You Don't Gap Spark Plugs? A: Ungapped spark plugs will cause misfires as the gap between the electrodes could be too small or too wide. The air/fuel mixture then may not ignite or ignite on the wrong stroke, which can cause misfires.
What happens if ignition timing is too advanced?
Spark plugs need to fire at the right time, which can be achieved by advancing or retarding the timing of the engine. Ignition timing advancing means that the spark plugs are firing earlier in the compression stroke, farther from TDC. The air and fuel mixture in the combustion chamber doesn't burn right away.

How Points Work
The ignition contact points serve as a trigger for the ignition coil. A small current flows through the points momentarily when they close, and this is what tells the spark coil exactly when to release the jolt of electricity that powers each spark plug.
Evaluation and Cleaning
If you're working on your ignition points, chances are it's because you're having trouble with them. When points get old, they often become burned, pitted, pimply or just plain ugly. In many cases, you can clean them up and use them for a few thousand more miles.
Setting the Point Gap
Getting the best gap between the points is essential for engine performance and reliability. Set the points too wide and the spark plugs don't get enough juice -- your engine whimpers. Set them too close and the engine works fine for a few miles. Then it stops because the points are so badly burned they can't perform their function.

How to set dwell on a car?
Your dwell, and thus your points gap, needs to be set before you get out the timing light. To set the dwell, remove the distributor cap and rotor, ground the coil wire and remove all the spark plugs from the engine.
What is the period of points closure?
The period of points closure is specified by the ignition system designer and is typically expressed as degrees of distributor rotation. In a four-cylinder engine, the angle between each ignition cam lobe is 90° and the period of points closure or "DWELL" is usually a bit over 45° of distributor rotation. In a six-cylinder engine, the lobes are 60° apart and the dwell time is 30° to 35°.
What is ignition point?
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. Getting the best gap between the points is essential for proper engine performance and reliability. Set the points too wide and the spark plugs don't get enough juice. Set them too close and the engine stops working after a few miles.
Does dwell affect timing?
The dwell, as well as spark plug gap, do have an effect on ignition timing. The later the points open, the later the spark comes and retards the timing. The earlier the points open the sooner the spark comes and advances the timing. That is why timing is the last thing to be set in a tune-up.
