how to set dwell angle with a multimeter

If you’re looking for a quick and easy way to set your dwell angle, a multimeter is the perfect tool! Just follow these simple steps and you’ll be up and running in no time.


In electronic testing, it is very important to know how to set your multimeter to the correct settings. The most common settings are volts, Amps, and Ohms. These are the settings that you will use most often. It is also important to know how to set your multimeter to the correct scale. The two most common scales are the AC scale and the DC scale.

What is a Dwell Angle?

Dwell angle is the number of degrees in the ignition cycle during which the points are closed. The dwell angle is measured with a dwell meter, by attaching the meter’s probe to the negative (-) terminal of the coil, then starting the engine and allowing it to idle. The dwell angle should be set so that the points just start to open (typically between 28 and 32 degrees), at the end of each dwell period.

How to Set a Dwell Angle with a Multimeter

One way to set a dwell angle with a multimeter is to disconnect the negative battery cable, then set the meter to the ohms scale. With the red lead on the dwell terminal and the black lead on the ground, slowly rotate the distributor until you get a reading of zero ohms. That is your dwell angle.

Why is Setting the Dwell Angle Important?

The dwell angle is the number of degrees of crankshaft rotation from the point when the spark plug fires to the point when it fires again. In a four-stroke engine, this will be two complete revolutions of the crankshaft or 720 degrees.

The dwell angle is important because it tells the ignition system how long to supply voltage to the coil before firing the spark plug. If the dwell angle is too short, the coil won’t have time to build up enough voltage and the spark will be weak. If the dwell angle is too long, the coil will overheat and burn out.

What Happens if the Dwell Angle is Set Incorrectly?

If the dwell angle is set incorrectly, it can cause a number of problems with your engine. One of the most common problems is that the spark plugs will not fire correctly. This can lead to a loss of power and efficiency, and in some cases, it can cause the engine to stall. Additionally, setting the dwell angle too high can cause the spark plugs to overheat, which can damage them.

How to Avoid Common Dwell Angle Setting Mistakes

If you’re using a multimeter to set your dwell angle, there are a few common mistakes that you can easily avoid. First, make sure that you’re using the correct scale on your multimeter. Second, be careful not to touch the probes together when setting the angle; this can damage the meter. Finally, take care to reset the dial before removing the probes from the spark plug holes. By following these simple tips, you can ensure accurate and safe settings for your dwell angle.
