Test the coolant for exhaust residue, but it sounds like a HG or head issue. No 5th gen Cummins yet. Also, I’d ditch the Cat oil filter for something that says Donaldson or Fleetguard. And if your fuel filters say cat, you need to change those out too. It’s been a long long time since cat...

Not sure it’s got anything tangibly better than the Donaldson DBL7349 already does. There might be a little more media, might, but most of that added height is likely taken up by the completely unnecessary bypass valve that isn’t even spec’d to be in the filter. In addition to the bypass being...

Single alternator. 2nd alternator would mount just above the CP8.

The commonly used Cat fuel filters are inferior to the OEM filtration, so the easier to change filter comes at the price of sacrificing filtration and fuel/water separation. Any company still using Cat filters for these trucks is clearly relying an Internet hype and/or hasn’t done any...

Yes there would be some continuity to ground, but not quite a dead short, just close.

The grid heater uses a chassis ground so the only wires connecting to it are positive.

I have not ever seen a diagram with both on the same side, are you looking at Hemi or Cummins diagrams?

3rd gen, 07-09 and they didn’t have the OEM 2nd alternator option.

There isn’t anything fancy about a dual battery rig when the are parallel, like these trucks. Should only + and -, nothing fancy. Likely tracing one of them will lead you to the positive voltage source and it’s disconnected from its load.

Uhhh….if they spark when touched they aren’t ground cables and one of them is already grounded and the other one is positive. Honestly appears beyond your knowledge, take it in somewhere. I’d just go to the dealership, have them reconnect the cables, find out what exactly they are and get the...

Google is smoking AI crack… the fuel filter is on the other side of the engine. I’ve removed things to get better access to the oil filter, but never any wires from the battery. What did the dealership work on?

Not a Ram, but started fitting my Arco A7000 and running the cables.

You would have to contact that company, but if it doesn't I am sure they will soon. I never looked into 48V since it doesn't make much sense in a van or RV, at least to me. Makes great sense if your loads are primarily inverted, but for DC loads I didn't see the overall benefit.

The only parts that are different on the dual alternator setup are the belt and 2nd alternator. The rest of the accessories, tensioner, etc are the same. Its a very easy mod to add or remove. The dealer or AlfaOBD/JScan (depending on year) can enable or disable the feature. I am pretty sure...
