Short circuit after radio wiring
Posted: Thu Nov 15, 2007 1:12 pm
Ran into a little problem after wiring in a new radio that I thought I'd pass on. I wired everything up and it worked great, until I turned the headlights on last night. The fuse to the dash lights and tail lights blew. Radio still worked fine. I had just added a switch for my glow plug control so assumed I must have a short somewhere. After pulling everything apart and finding nothing, I went to the mdocuk forum and found out that there is a wire to the radio that acts as a ground until the headlight switch is turned on, then it is 6V - I assume for a radio light. It does not get power when the ignition is turned on. I had wired the ground from the radio to this source. Lesson learned....
