Disappearing voltage?

[jwedell]

I would start by checking the circuit breakers, both the main and the ac breaker for tightness (loose connections can build up heat and cause a voltage drop). I also would check the neutral for tightness (same reason). Also at the CG outlet you could have had a loose connection, and if the extention cord at home was too long that could give you a voltage drop by overheating. Good luck in your trouble shooting. If i can offer additional help post it or PM me.
