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?

The unit of measure for AC voltage is [volts, AC]. To measure AC voltage using a benchtop multimeter, select the “AC V” mode and connect your probes.

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.

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

You could just check this by measuring the voltage across the battery - it will drop several volts while a working starter is engaged. No voltage drop on the battery suggests no current to the ...
