Thanks Ronnie, you're very kind. Unlike yourself, I don't have nearly as much experience a mechanic but I still should have known what I was doing. I have quite a bit to do around the house tomorrow but will check all the other fuses on Wednesday, weather permitting. Once the replacement positive terminal arrives from Jim I'll install it and, cringing with crossed fingers, connect the battery and let you know what happens (or doesn't happen.) Regardless of the outcome, I'm committed to seeing this through.
Again, many thanks, you've made be feel little better.
