1997 LNT8000 Alternator issues

Hello everyone looking for some help on 1997 LNT8000 dump truck with 8.3 Cummins. I’m currently looking for a wiring diagram electrical system/alternator if anyone can point me in the right direction or has one? The truck is currently going through alternators once every few weeks. I need to track down the problem and fix it. Truck has fairly new batteries, I check for parasitic draw and nothing is staying on. Checked the harness going to the regulator for broken or bare wires and everything looks fine on the engine side. Thoughts and things to do? Any help is appreciated thanks!

I would start by having the batteries checked for dead cells or direct internal shorts ..
they would cause the alt. to max charge all the time and overheat ..
Good Luck Steve
