I don't know if I missed the part where someone covered it(and I'm aware this is an old thread), but I see it was mentioned that the 48v system charges the 12v system in the Ram. This is where the problem is. You don't want to jump start a vehicle with a traditional alternator with a vehicle that does not have a 12v alternator. The alternator's voltage regulator smoothes the power being introduced to the vehicle. It's possible that the alternator on the other vehicle damaged something on the Ram because of this. I would expect something similar if I jumped my VW from my Tesla. It's why I keep a jump box around in case of a dead battery. You don't want to introduce dirty power into a system that does not have the ability to safely accept it.
Nevermind, all over a plug. . I'd still be careful jumping from this type of electrical system.
