bufbooth Posted June 23, 2007 Share Posted June 23, 2007 I have a 1990 Toyota Odyssey and it has a Winegard DC plug outlet to power a TV. I openned up the Winegard outlet box to see if I could wire in a fan and in the process of putting the metal cover back on the box, I pushed it down too far (missed the lock points) and the cover ended up touching the positive wire, causing it to ground out. As a result, I no longer has any power (should be 12 volts). I figured that I blew a fuse. I checked the two fuses under the sink area and they were fine. I checked the trucks three fuse boxes (the 10 or so on the drivers side, the two on the passenger side, and the 6 or so under the hood). All were okay, I used a meter to check them. I was able to test the ground and positive wires going into the Winegard box and the ground is fine, but the positive is dead. T It sounds like there is another fuse, but I cannot locate it. Does anyone have a suggestion or a wiring diagram? Thank you, Dennis... Quote Link to comment Share on other sites More sharing options...
keitholivier Posted June 24, 2007 Share Posted June 24, 2007 Ah, Mr Bufbooth, so you have a name.. Howdy Dennis. I don't know your version of the motorhome but do you not have a separate coach battery housed somewhere in the coach ? In my Dolphin everything in the coach is dead if I disconnect the coach battery. Find the coach battery. Sometimes there is more than 1 set of wires going to the + terminal and often you will find inline fuses right near the lug on the battery. I had an inline fuse (cylindrical type) that had a rusted out spring, hence there was no contact whatsoever with the fuse. I replaced it with a modern spade type inline fuseholder. Unless you are running something off the main battery, don't bother looking at the cab/chassis Toyota fuses. Keith Quote Link to comment Share on other sites More sharing options...
bufbooth Posted June 24, 2007 Author Share Posted June 24, 2007 After sleeping on it, I took another review of the motorhome and realized that on my curcuit breaker there was a small 4 x 4 inch panel that was bolted down, and in small print there was a label that stated DC replacable fuses. Sure enough, I took the panel cover off and there was 4 fuses with one of them blown. I replaced the fuse and all was well. So, my motorhome has two fuse boxes under the hood, two fuse boxes in the cab, two inline fuses under the sink, a curcuit breaker (5 curcuits), and a 4 fuse panel on the curcuit breaker. Dennis...

Gottasmilealot Posted October 5, 2007 Share Posted October 5, 2007 Aside from the fuses at the electrical panel area, I have one inline 12 volt fuse where the battery box wire comes into the rig. It's under the dinette seat in my rig (which has a rear dinette). It drove me crazy for a while too until I found it. Quote Link to comment Share on other sites More sharing options...
