Forget about the term 'throwing a switch"  I know it means On'  Not sure about only getting voltage on one side of the line, with the switch closed.  I just figured that the switch when closed, is taking the meter out of the circuit, through the path of least resistance.  How is the meter getting voltage only on one side of the line with the switch closed.

The link takes me here "SMFHacks.com" and it asks for me to register and log in, and doesn't give any clue to appliance repair study manuals, so unless I know what the page wants, I won't register.  I tried the left column of this web page and the link on the thread in this forum but I still get the SMFHacks page.

I was explaining it to a friend at work and he said, I see, Oh Yea.  He use to do refrigeration work, and it took him a while to get it to.

oh well, the guy I know hasn't done refrigeration work in a while.  For a while he worked on vending machines, but I guess that was a while back.  As far as one side of the line and the meter reading 0 voltage when the switch is closed the only thing i can come up with is that one side of the switch is hot and one side is negative.  So when the switch is closed the meter reads 0 volts.  I guess that thevevinms, can't spell his name, law is in effect here.  Voltage in equals voltage out in any two node points.  Oh well, works for me.  Whatever!

The voltage is called alternating current for a reason. A flashlight battery always goes from positive to negative. Not so with our AC friend. It constantly changes its mind. One millisec it is neg and one millisec later is it positive. The alternating current is purposely so to keep wires from getting too hot. So if you are checking a circuit and you come across a bad part that opens the circuit you gonna get a voltage reading because the current is constantly alternating from one post to the other. If however all is kosher there won't be any voltage read because only one side of the current will be in the mix.  The current will be moving in one direction only. Sort of like being in a sailboat on the lake. You are moving along fine till you decide to turn around. Kapeesh?
