Electrical Demons

Ok. Driving to gas station, go to leave, batt is dead. Try and jump it and welded the jumper cable to terminal. :fire:

Problem. :frustrate

Disconnect lightbar wiring and jump again, starts and runs fine.On way home radio shuts on and off, usually when i apply brake. Using hi-beams cause engine to slow down.
Go to pickup batt chager, leave it running, go to shift outta park and it dies. JUmped batt from f150 for 30 min and i got nothing, just frantic flickering of lights and clicking from something (i dont think it was the starter sol.) :frustrate

Im going to check everything with volt meter, repalce any bad wires, replace alternator and try again.

Also, alternator, battery and starter are new within a few months, havent been in mud ever.

Anyone been here before? Any tips on where to look for the cause of my alternator burning out? (I believe thats main part of problem.)

auto zone, its OEM replacememnt. I found a short, the line thaqt runs from starter sol to alt was welded in half, completly fried, wrecked alt. Im going to use another alt i have laying around, same kind and try with the same battery. My batt is running low at 11.8 volts, but starter sol, alternator and starter wire was all reciecving same voltage. I checked the starter wire under pass side fender and got 11.8 volts, but at starter itself i put pos to the ring terminal and ground to the frame and got nothing? so short between there and the other test site right?

exorcized demons. I got a new battery and alternator and the cable that runs from the alt to the starter sol. and it started right up. What i think the problem was is that the insulator between the hot wire from the alt and the alt itself failed, and the current arc'ed from that pole to the alt casing, effectivly grounding the circut and welding everything in sight.
