For sure. Mine didnt have any corrosion that you could see. I assume these are just super sensitive electronics and that slight loss of ground was enough to cause chaos.

I would 100% fix that before i continued. Mine was not cracked and was still pretty tight but i could force it to move. The others i couldnt. Would be a cheap and quick way to rule something out.

I was actually waiting a couple days to be sure i was getting accurate results before posting this but since i have someone else struggling with it.. i went to do the apps sensor reset procedure the other night. I had never heard of it till a few days ago and thought it was worth a shot. Part of it is unhooking the battery cables and draining the power. Well before i unhooked the batteries i decided to tug on em side to side and see if i could get any movement at all. Well one of my ground cables very slightly moved. I tried tightening it but it wouldnt. EUREKA! Ran to another truck of mine i had just put new ends on and grabbed one. Cut the ground and put the new end on it. Went through the rest of the reset procedure for the apps and started it up. It ran twice as smooth as before instantly. Threw it in gear and the second i touched the pedal i could feel the power. I drove it to work the next day and boy lemme tell you this thing will run.. not one stutter and straight lines on my voltage trends. After the first day my stutter started to come back but my trends are all still straight which tells me i must have fixed the grounding issue but probably need to replace the apps. I was going to wait until i fixed it and it stayed fixed but figured id go ahead and share so you know theres still hope. Thank God!

Checked my batteries this morning. One is marked 07/24 and the other is 08/24. They must have replaced em right before i bought the truck.

Not sure on their age. They were in it when i got it. Thats something i can check when i get off work in the morning. Ive had no issues so far out of them as far as dying or having a hard time starting. As far as the cables everything looks ok.

After the collision i limped it home. I was in shock (i spun around all the way off the hill and barely dodged going off a cliff, no pun intended). Due to the shock and just barely limping it home so i could get a look at the damage im really unsure if it started immediately at the time of the wreck. It also doesnt help any that the vp44 went out within a mile of my house after driving it the first time after the wreck. So they kinda happened simultaneously. The red and white wires in the PDC i mentioned are the ones you brought up that run voltage to the ecm and VP. Ive been doing all of my electrical testing when the truck is up to temperature so my trends are going crazy in an effort to be sure my testing stays consistent and to know the problem is actually there at that time. As far as the grounds go that was my intention with the ground leads. I was just trying to bypass any bad ground i could have to be sure that was not the problem. Like i said the trend seems to slightly react and smoothen out for a moment after hooking up the ground leads but then returns to what it was doing. As for the W-T ground mod i just found out about it the other day. That is my next attempt at this but at the moment im working 12 hour swing shift for the next couple weeks without a day off so it will be a minute before i can get that far. If it wasnt my daily driver i could do it after work but would hare to mess something up and have to borrow a vehicle for the next day. If you google it there are videos that show it. Its basically a way to “delete” the splices between grounds on these trucks. Supposedly helps with a/c noise and gives you better grounds where you need them from what i understand.

I purchased my first dodge cummins in December of last year. It is a 2001 3500 4x4 NV5600 with at the time 112,000 miles. I drove it 6 hours home without any hiccups other than the crappy steering which i have since fixed. In January i wrecked the truck coming off of a completely iced over hill and ran backwards into a rock wall doing 55+ mph. The truck drove home afterwards. Once i got it home and fixed the busted lights, the vp44 went out all at once and it died in the road. I install the upgraded thoroughbred diesel VP44, billet tappet cover, and a fass 165. My truck has not ran right since. It has a stutter now. When between 1700-2200 rpm it will randomly stutter almost like its cutting fuel for a split second. In the process of tracing down the problem i find out with my scanner that once my truck warms up to operating temp all my sensors go nuts. All sensor voltage, the ecm voltage, and the vp44 voltage will spike straight up and down repeatedly going from full voltage to no voltage until the truck cools off. I dont believe the 2 issues are completely related because the stutter is there even when the voltage trends are showing good. I have had multiple people look at it, spent countless hours testing voltages, moving grounds, hooking and unhooking stuff, and even sent my ecm off to be checked ($600) and can not come up with a solution. I want to love this truck so bad but i cant even remember what it was like to drive when it was doing good. Please someone help me diagnose my issue. I think at this point it could even be the fact that i am so deep in i could be overlooking the obvious. Just an fyi i have a fuel pressure gauge inline around 1.5’ before the vp44 that never drops at any point. It shows a constant 15 psi. I have tested the red/white wires from the pdc and all show almost 14 volts even when my scanner is showing dips. I doubt it had anything to do with it but my rear abs sensor is out. Havent got around to replacing yet. All the issues occur with or without the edge comp box. So far i have ran let the truck idle while watching the trend and unhooked my map sensor, abs module, and coolant sensor. Even with each or all unplugged the trend stays the same. I have taken alligator clip leads and ran grounds from each of the factory grounds to the frame, ran grounds from each of the factory grounds to the negative battery post, and hooked the negatives from both batteries together in the process of trying each factory ground. The trends seam to slightly respond when a new ground is hooked up but only for a couple seconds.
