I bought a boat/trailer last year. The first time I put the boat in the
water a fuse blew. My dealer said it was a lousy hitch installation and I
had to have him replace it. The hitch installer said everything was done
properly. I figured something shorted when it got wet, so the second time
I disconnected the electrical before putting it in the water. It was okay.

Yesterday it blew the fuse before getting to the water. Argh. (92 and the
A/C went out, as did the speedometer...)

I presume something is shorted on the trailer. Any suggestions for
troubleshooting it?

Something is miswired in your tow vehicle. The AC fuse shouldn't blow. The
trailer may also be miswired
