How To Test An Alternator? Using A Multimeter The easiest way to test an alternator is by using a multimeter. If that’s a tool you have on hand, just follow these instructions: Turn off the engine.

Testing the DC voltage output of the power supply using a digital multimeter can help you isolate any potential issues and determine if you have a bad power supply.

Record the voltage that appears on your multimeter. If your power supply sticker shows a voltage of 135 volts, you should be seeing the same reading on the multimeter.

Diagnosing a faulty transmission speed sensor is pretty straightforward, as is replacing it, but to diagnose a problem fully, you’ll need to be comfortable using a multimeter to check voltage.

Seriously, what setting do you use to test a spark plug wire? Which ports do the probes attach to? How do I measure alternating current voltage?

In this article, I’ll show you how to use a multimeter to troubleshoot some basic electronic components, such as resistors.
