Rain was causing problems (fixed for now)

I must have some wires that sitting in a puddle. The rain has been causing the ground fault interrupter to trip so power has been going out on the lights. Apologies if the lights are out when you go try to see them. I need to find the trouble spot so the tripping stops.

I can't find any obvious single large ground fault. I think there is a little bit of current leaking in a lot of places. I've split the circuits of five GFCI (instead of just one). The hope is that each smaller chunk will stay below the trip threshold of the GFCI.

The workaround appears to be working (although the weather has also been cooperating).
