Lol. Yeah I guess I thought there was more to it than that.

Like if you use a loading meter on computer controls it can foul components.

But it makes sense now.

Thanks

Yep saw video with you testing connectors warning of ghost or junk readings.

So what happens when you measure VAC at a motor using a DMM?

Aha! Sorry I’m with you.

I tend to over think things and jump ahead.

Thanks so much for all your help!

I believe so…

At first I thought maybe when current actually flows the voltage goes away and becomes amp flow.

But you helped by explaining (I think, tell me if I’m wrong) that when we measure voltage we are actually measuring potential difference between two points?

So with switch open there’s 120vac at L1 and 0vac at N so it measures the difference of 120vac.

With it closed we get 120vac at both L1 and N so difference is zero.

I’m I thinking about it right now?

By proving no voltage difference with switch closed you verify 120 is also present at motor. Correct?

Thanks for your help!

Total circuit wattage drops but wattage at loose connection increases. Does that help?
