My Kingdom for a simple Fuse

[SuperSnoop]

Like Jayhawk said, you need to look at the wires connected to the black and white wires.

I did a lot of sprinkler repair this week. One elbow joint, one T joint, one four-way, and one extension. The elbow was easy, but the others required uncovering about 10 feet of pipe to get enough flexibility to connect everything. Yes, a big PIA.
