I am a complete klutz when it comes to electricity so need help even with what seems like it should be a very simple problem.
When I moved my Prodigy from the old truck to the new I followed the directions--I'm pretty good at that--and everything works. But the new truck has the trailer tow package that came with its own harness--which I didn't use--and a J case 40 amp fuse that was to be installed in the underhood electrical center. Since everything on the Prodigy worked, I assumed the fuse was to send 12V power to the trailer, plugged it in and promptly blew it. My voltmeter indicates I don't have 12V at the 7-way truck end.
This weekend we went dry camping for the first time so I thought I'd try and get power from the truck again. I disconnected the -ve from the battery, plugged in the new fuse, reconnected the battery and promptly blew the fuse again.
What am I missing here? doing wrong etc.? Assuming there's nothing wrong with my virtually new truck, what is the proper procedure for installing this fuse? Almost forgot--I also have the camper wiring harness sitting unused up on the gas tank.
