You want to connect to the opposite terminal on the ACR from the one that goes to the batteries like I said earlier. But the easy way to figure it out is check continuity of the existing wiring.
Mine has 4 awg on both the line and load terminals - and yet, the wire from the truck is only 8awg. Odd.
But I am of the understanding that I should remove the ACR completely and replace it with this MPPT/DC-DC charger. If so, I would just move the load cables from the ACR to the charger and run a new 4 or 6 awg directly from the tuck battery straight to the line, or incoming, terminal on the charger. Am I misunderstanding?
Ok yeah that’s weird as I can’t think of where the 8ga in would be spliced to a 4ga before the ACR. ACR should be first thing in line.
It’s just an automatic disconnect from the truck 12v power. ACR is just a voltage sensing relay. If it sees +13.6v or charging voltage when the truck is running, from the source it latches and provides power. If not it unhooks from the truck when the engine isn’t running.
DC DC charger could run after the ACR but ii presume they already perform that function.
