12v symptoms I don't understand
Today while switching out 12v batteries my wrench momentarily shorted positive to trailer body (it sparked a little), I already had negative connected. Since then it appears that I only have 12v power...
Forum Discussion
Solved!
Let's see if I can describe this in a clear and succinct manner...
First, the untold prequel:
Several days ago I started troubleshooting my furnace, it is sometimes not firing, the fan will run but it was having trouble catching. I had the furnace out of the cabinet for bench testing. It blew two fuses. As part of my troubleshooting I switched out the battery and that's when I shorted positive to frame and my problem that I brought to the forum began.
So, fast forward to today, thanks to help from forum members I traced down and found the loose wire in the thermostat, very cool and many thanks. But the fridge... After reading recent suggestions and talking to technical staff at the manufacturer I went back out to the trailer. I determined that the two fans were fused independently and NOT to the fridge. I noted that the 12v wire at the fridge was grey and, looking at the back of the fuse panel, I saw two grey wires. I counted down from the top to match these two wires the their respective fuses. The first grey wire was an unrelated circuit and the second was in position 10. Wait, I only had 9 positions labeled on the front of the box, what was position 10? Could it be the fridge circuit. I popped a fuse in and, yes, that was it. I then realized WHY there was no fuse there. I'd taken it out earlier when the furnace blew fuses. I mean, it looked like an extra fuse in an unused and unmarked terminal. So, it turns out that I had caused my fridge problem by unwittingly removing the fuse. I also possibly protected the fridge form damage by removing the fuse prior to my arcing accident.
I hope this makes sense. Please ask questions if this is less than clear. I really appreciate the help here.
