I have a 1999 dodge 2500 w the 24 valve cummins. The truck got vandalized and the meth heads cut the wiring harness in atempt to get the copper. The guy spliced it back together. When he started it he drove untill the bat died. Has tried replacing alt nothing replaced the pcm still nothing. He said there was 4 brown wires w a white stripe that are grounds n have no order to how the hook up. All fusesand relays check out!! Has had it in a shop spent 400 on nothing. He couldent Fig it out!!! Someone said try generizing the alt to boost it that sounds retarded. CAN ANYONE HELP ME!!!! Im getting the truck cheap hope its fixable will start and run great. Till bat juice is gone.
