Yeah, I went to the 30 amp main fuse in the battery compartment first. I pulled it out and metered it. It was good. That was why I found it so surprising. I expected it was the main fuse. When it waasn't, and I was striking out on everything else I could think of, I came in the house and posted the question. I went back out and started following the voltage, and then realized that what I thought was the main fuse, was actually a spare fuse on the front of the main fuse holder. Presto! When I popped the cap off the real main fuse, I found it was toast. I had another 30A fuse in a box and that was the end of that. Thanks for the help fellas!
