Sorry to hijack here (although could be what the original poster was getting at) but for the purposes of a CTEK D250SA (or similar DC-DC Charger), does any wiring need to be done to account for a “smart alternator”? I noticed my CTEK has a couple of wires that seem to be only for cars with smart alternators. I’m gathering from this thread that the alternator itself isn’t actually very smart but there is some smart things going on behind the scenes

I have a ctek250S and it needs nothing extra. I think it stops taking power when main battery drops below 12.5v. Your SA version is probably similar as it's just got the added benefit of higher output voltage for AGM. I simply use the existing rear socket wiring to run the ctek in the rear. Fuse selected for always on. Been running since 2012.
