No power to cab after pushing horn button
Just like the title says. I put a set of Caddy horns on the truck a couple years ago and they have been working fine until yesterday. I pushed the horn button then all power to the cab was gone. I checked power at the fusible link junction block on the RH fender, got power from there, checked the 4 amp fuses on the ammeter circuit, they are good, got 12.5 volts at the hot post on the alternator, but that is as far as I got. The truck started fine before, no electrical issues at all. What's next, check the horn relay?

Re: No power to cab after pushing horn button
I figured out the issue. I had removed the bulkhead connector to add a power wire for efi and I didn’t tighten it back up.
