Ty American Truck, after at least 100 other searches on KZfaq, I appreciate this video so much.

Great video. A lot of detail and you know what you are doing. Just came through as my son is having a no crank issue. Thanks.

great communication and a good fix....and, an ideal theft prevention idea is beginning to form in my head

Hi Dom soak up all the knowledge its the good stuff

So man I’m in same position got my dash torn apart replaced starter and relay well then I noticed no square around park symbol I kept telling buddy’s that we’re working on it no one payed attention i knew that had to be something so is it the roster come and that wire or just roster comb. Good video definitely helpful thumbs up bud

I’ve got the same exact truck and it’s doing the same exact thing. We just replaced both batteries and the starter and all of the battery cables and it’s doing the same thing yours did. I kind of suspected it was something with the neutral safety switch as we tested the relay yesterday. I’m gonna go back and do what you did and see if that fixes my issue.

I have a 06 2500 w/ Cummins. I dont have a relay like you were showing (around or under the fuse box). any idea where i would need to connect the wire to?

Thanks man that was the exact problem but I did find the broken wire it was in the harness next to the transmission. Now that that's fixed truck starts but I do not have any indicator lights or drive or any other. And the fun goes on and on

Nice find looking to put a kill switch

I have the same truck. the truck wont start in park, only neutral. If I open door when in park with motor running the horn starts beeping and if I put in 1st with motor running the truck shuts off. Am I looking at a nightmare?

I believe the ECM controls the grounding signal to the start relay? If the ECM works fine for everything else, then yeah, the ground splice is probably an easy fix over spending $1k on a replacement ECM.

So you dont have any lights on the cluster before you run the ground cable ..??....I have 07 dodge 2500 cummins 6.7 motor with same problem dont tur over dont crank . Any light in the cluster just the red light flashing .do you think the same part is bad on my truck .

men thanks to share this information it is a great help my transmission blew to pieces and i need rebuild it but before that need to start the engine again, hope it works on my 2500 2007 , can give one opinion about the true to resolve the problems of this trucks better option is swap to manual ? what transmission can works ? thanks have a great day follow you from argentina

I’m having starting issues with my 06. I did the Allison 1000 swap from Caconversions it shows PRNDM1 on their gear indicator but on the original gear indicator the boxes are blank and won’t start. I used a jumper wire that feeds the solenoid and it starts and works fine, I called them they told me to check all the wiring and I did, everything looks good. The weird thing was the gear indicator was working but only on the (1) on the trucks indicator. I would turn the key forward “quickly”and it started now it doesn’t do anything anymore.

So just to be sure I’m understanding correctly, it is more then like a short in the wire somewhere? Correct?

Whats the official name for the rooster comb?

Seabees!!!!
