1982 BJ44, 2B engine, 24v.. So, 5 months ago, I had 5 short trips, headlights, wipers, and heater going for 50 minutes, and it wouldn't start.. AAA tried a jump and replaced 1 battery, then towed me. I informed him it was 24V, but don't know if he attempted to jump me at 24.. Mechanic said starter, but it tested fine, so bought a new 24V regulator.. Remaining battery looked like it was overcharged, so replaced after getting alternator back in. When I hooked up battery, spark was so hot it fused the terminal to post as soon as I touched it. Old battery is still fully charged, so this can't be a grounded wire, right? If a hot wire was grounded, both batteries would be dead, not fully charged.(damn close to full after a week, so not a bad ground).. So, what can possibly be left here? Starter is the obvious choice, any less obvious things I can easily check?? I didn't want to leave 2 new batteries hooked up without being out there, there's always the chance of a wire getting hot and causing a cascade, at least in my mind. Electric isn't my strong suit, I'm hoping someone else had the same thing happen and resolved it. Before I replace a starter, I'd like to be sure that's what this is..
