Does anyone know how the voltage regulator and alternator works on these rigs?
Are they essentially a voltage source, at about 14.5, until they reach the current limit, then the voltage drops? I'd go take some measurements, but of course my van is in the shop :crying:
Or do they have some battery charging smarts or circuit such that the voltage drops when the load drops so the battery is not overcharged?
I'm wondering what it will do when connected to an auxiliary battery. A lot of current would be nice for bulk charging an AGM, but I don't want to overload the alternator. The diesel alternator is 220 amps, so I would think 100 amps for an hour or so would be fine.
