PCM problems in 12v
 

I lost my tach, OD, charging, AC ect. which are all signs of the PCM being bad. I checked all grounds the rest of the wiring on the truck and found nothing wrong. So, I replaced the PCM in it and now it will start up and it just blows the engine fuse after about 10 seconds, and still wont charge at all.

Does anyone have any other input on how to fix this? I've spent countless hours researching this online, brought it to two different dealerships and called 4 different diesel shops and nobody can figure this out. It been over two months without it and this is my daily driver.

I would apreciate it!

I don't know about the engine fuse blowing but the no charge problem could be the crank position sensor have u replaced it yet?

did this ever get fixed? if there is any obstruction around the alternator wiring it could easily be causing the fuse to blow out
