The outlet in Bathroom 1 has a GFI. There is one line feeding the line
side, and there are two lines on the load side. This same GFI is used
for the outlet in Bathroom 2 since the BR2 outlet loses power when the
GFI on BR1 trips.

The GFI is tripping even with nothing connected to either bathroom
outlet. The problem is that there is obviously something else connected
to the circuit, but I cannot figure out what it is. As I said, there are
two lines on the load side of the GFI. One of them feeds the outlet in
Bathroom 2. I have no idea where the other one goes, so I can't find out
what on that circuit is causing the trip.

Even further, there are two lines tied together on the Bathroom 2
outlet, as if something else is fed off of that outlet. How can I find
where the other wires go? They're in the wall. The GFI is not bad. It
was just replaced. It doesn't trip if I power the GFI but leave the
lines on the load disconnected.

What else is likely tied to the GFI?


There's an inductive load on the same circuit, and when it switches
off it's creating a voltage spike that the GFCI doesn't like. (my
bathroom fart-fan trips the GFCI every once in a while when I switch
it off (and it's not connected thru the GFCI, just on the same
circuit and taps off at the same junction box)

Something with a motor, and a switch that *snaps* off.
