yes, i tested each output of each circuit breaker (where the black wire connects to the breaker), there is power. It's not the breakers.
Every breaker is accounted for. Meaning, we have discovered that when a breaker switches off, so does some light or plug somewhere in the house.
So this leads me to think that somewhere along the circuit, it's interrupted and not supplying power to the other 3 plugs and one switch, which controls a bathroom fan.
But, this has me baffled, and makes me think that the manufacture home electrician, when the house was built and wired, screwed up. You would think that one of the Romex's inside the box where that GFCI was, would be the supply wire going straight to the breaker, but this is not the case. I have a feeling, that somewhere, there is another plug in the house that is wired directly to the breaker, and then from there it goes to the GFCI. ANd between that plug and the GFCI, the wiring is broken.
Why they wired it this way, I do not know, but if the GFCI was wired directly, then one of those breakers in the panel box would not be turning on/off any other plug/switch in the house. But each breaker does do something as the wiring sits as it is now.
I think I need to start at the GFCI box, find out where that Romex goes, and back trace the wiring somehow till I find the problem. I am guessing that the other Romex in the GFCI box is going to the switch, then from switch to outlet box outside, then from there to the switch in Bathroom B. And that is where the wiring ends, as there is only one Romex going into the box in Bathroom B.
There are two Romex going into the GFCI box, Three Romex going into the switch box. There are two Romex going into the box outside, and one Romex going into the box in Bathroom B.
I will check this tomorrow with the multimeter, but I am guessing that the 3 wires in the switch box in bathroom b, next to the GFCI, one goes to fan, one goes to GFCI box, and the other to the outside box. Then, outside box to bathroom B. So, with that said, I am guessing that the other wire going into GFCI box, is the supply power, and that is where the supply line is broken somewhere. I need to trace where that Romex goes.
Yes, the discoloring happened at the time the circuits stopped working. The extension cord was not left in a Pond. However, a 6 way outlet strip had his pumps and filters plugged into it; probably overloading the circuit. But, that is not all, I recently discovered that that outlet strip caught fire, half melted and sitting in a pool of water on the ground. Like I said, my stepfather isn't too bright. Using an indoor outlet strip outside, with no protection from the elements, that, and the lid for the outside plug on the wall was left unprotected as the extension cord was plugged in. I have bought him an outdoor outlet strip with a timer, but, need to get the outside outlet working again so he can plug it all in properly, and yes, I purchased a new outdoor cover for that wall plug as well, so his extension cord can stay plugged in, even in the rain.
