You need to have a voltmeter like this one

And you need to know what the 3 connections are in your AC wall outlets. White is ground and the white wire here goes back to the breaker panel and connects to a ground connection and the opening that looks like a mouth below 2 eyes is also a ground that connects to the breaker panel ground through the green wire.

Note the smaller of the two plug connectors is the hot wire that should measure 120 volts AC or close to that.

One of the first tests is to use the ohm meter to test if the white wire and the green are both truly connected to ground and to each other. Easiest way is to connect one meter wire to the tall prong slot and the other meter wire to the “mouth” opening.
