I have a 07 ram 2500 6spd v8. One day it just stoped like no dash lights, no power, no electricity works at all. I have checked everything I could think of. I got a new battery, I had just put a new starter and alternator in it and it ran fine after I put them in. I even checked the fuse box where I use a light tool to make sure it has power showing. It still doesn’t work? Does anyone else has any options. I don’t want to junk the truck- it is in Great condition. No rust, good frame and only has 50k miles on it. They only down fall has been the day that it stopped turning on.

 

Sounds like a CTM issue. Disconnect the battery, short the leads and turn the key, then reconnect (or leave disconnected overnight). See if it resets it.

 

Your 2500 is gas or diesel? I would start with rechecking you connections at the starter and alternator. Use your test light and see if you have battery voltage at those connection. Do you know if the truck has fuse able links? And look inside the cab under the dash on the driver side and make sure you don't have a connector that came loose.

 

It is gas and yes I checked those connections and they were good. I will have to check under the dash and see! Thanks
