I can only try-
Question for you-
I bought a Craftsman digital voltmeter so I could fix the refrigerator. It’s much more advanced than the one I used as a kid.
There are two wires (black and red) but three holes- grey, black and red. I’m curious to know what the grey one is used for. There is a warning on it- “10A For 30 sec. MAX every 15 min. FUSED”. I have no idea what it means but I’m nervous to experiment.
Can you shed any light?
