06 Cummins, and I've burned thru 3 batterys cannot figure out what the problem is, put it in the shop and they changed the wires, still having the problem, ideas??

 

Common problem. Change the alternator, I'm betting it's been the passenger battery every time?

Mine just did this, changed the alternator and put in new batteries, no issues since.

 

Yeah passenger side, thanks!

 

Alternator and/or voltage regulator

 

Unfortunately, you spent alot of money on replacing your batteries in your truck. What's annoying is the people, I won't call them "mechanics" or anything related to the title, replaced the wiring as if that's going to fix a battery issue. They should know better and most likely they do but they want you to throw money at trying anything and everything to pad their pockets.

The actual problem, which you could have found out by searching online because it's a very common problem with dodges. The dodges have a Temperature Sensor, which is mounted in the battery box under the battery. It goes for roughly $40 at O'Reilly's, Autozone, etc but $14 at Rockauto.com. Keep in mind that it could also be the fuse for the Temperature Sensor. If the fuse blows then no Temp Sensor lol. Also, clean the battery box so the new sensor doesn't short. I had to replace the battery cable clamps because the corrosion had dissolved them completely.

Remember, don't trust all mechanics, unless you know them and/or they've proven themselves but previous work. Also, research online first, then YouTube how and use common sense for everything.
