Thanks 800XL, I'll look at that also. A belt squeal lead me to a frayed alt belt, that led to a bad batt, that led to an alt that has a faulty regulator. When I get that fixed, then I'll go back to that. But I hadn't thought of that as I figured a fuse somewhere along the line would have blown. Neither in the fuse block nor the little fuse in the tip of the device plug blew. I want to upgrade the alt capacity and batt to be able to easily add accessories like a winch or extra lighting. So I'm looking for a good upgrade for those.
