I've got a good friend with a 2005 Dodge 3/4 ton 4 x 4 5.9 Cummins he uses daily, pulling, hauling daily driver etc. He tells me every so often his batteries end up dead overnight. He's checked the common stuff, interior lights etc. A couple of local mechanics have convinced him the computer integrated voltage regulator is the problem and he's now intent on wiring around it, up to and including trying to put a 1 wire Delco on it. I'm not convinced it's the regulator since it's intermittent. I've not found a lot on the Dodge forums addressing the issue. I told him to call me sometime when it does it and we'd put a charger on it and I'd go through the fuse boxes and see if I can see the draw but our schedules haven't matched up yet.
Has anyone run into this before? Any input would be greatly appreciated.
