Does the second alt still need some connection to the truck "brain" so charging is disconnected when the truck is turned off, so doesn't drain the truck batt. or is it not hooked up to the trucks "brain" at all and a stand alone automatic or manual on/off switch installed in-line?
My 2017 Ford has dual alternators as that was required for electric cabin heater, but from my research the 2nd alternator is integrated part of the system and not easy separable.
My Sprinter has electric cabin heater as well, but 250 amp alternator solves the need for more charging.
What I mentioned is that on Sprinters - owners who go that far add 2nd alternator with independent house charging system.
Again - this is for people who don't mind to spend few thousand$$ on the projects and no offence, but average Sprinter owner seems to be well better educated than average TC owner.
Bottom line - such project is not for just anybody.
