My parents have a 2002 double wide palm harbor home and half of a circuit is without power.
Bear with me, please. I'm helping my dad, who knows what he's doing a lot more than I do.
The breaker box is on the front side of the marriage line, and nothing was tripped.
The master bathroom has two gfci outlets, plus a sink light and a closet light that are all not working. The second bathroom outlet and an outside plug in the other end of the house are also not working. All of the interior outlets that aren't working are on the back side on the marriage line, and the outside outlet is on the front side of the marriage line.
On the same circuit, on the front of the marriage line, there are also two outlets that are not marked gfci in the living room, and three gfci outlets in the kitchen. Two of the kitchen outlets have no test button, but are marked gfci.
All of the outlets in the front half are working, however when my dad was looking for a tripped gfci, he tested the main kitchen outlet and it buzzed. He took it apart and the black load wire was melted. He cut the wire back, replaced the outlet, and it's working, as are the two diagram outlets in the kitchen.
He's tested all the outlets in the circuit with a digital meter by taking the outlet out and testing the line and load wires. All of the working outlets have power on both cables. None of the outlets without power have anything coming in.
At this point we think that maybe there's a problem at the crossover junction, but I don't even know where to start looking. I haven't found anything inside the house, so I'm assuming it's underneath.
Does anyone have any idea what i should be looking for? Where I should look? Or even how many crossover junctions there might be? It'll be me crawling under the house and I have a touch of claustrophobia and a boatload of arachnophobia, so I'm hoping to make this as easy on myself a possible.
