So my BJ44 died a few months back, AAA replaced a battery, then towed me.. I pulled the starter, and it's fine, the old truck mechanic said most likely needs voltage regulator, so I got that, and a second matching battery.. When I try to connect the 2 batteries(+ to -), it's way too hot, actually melting the terminal and sticking.. So, if the batteries are fine, voltage regulator is fine, and alternator is fine, why is there so much juice when I try to connect the 2 batteries? What do I check next?? Thankfully, I see no smoke, I smell no smoke.. Even if I'm supposed to connect the 2 batts first, then the starter, it's still happening.. Not sure if this matters, but had to try. Any help greatly appreciated.
 
Hey man, did you get any resolution to this? It sounds like your system is arcing to something.

Does it overload only when you attempt to start the vehicle? Or just when you attach the terminals?
