Iota conversion to blue sea ARC

I'm confused. The Iota is a battery charger that runs off of shore power to charge your camper batteries. The 7622 ACR is a relay that protects your battery bank(s) from draining each other by disconnecting them if either the camper or truck batteries get too discharged. Most of us have BOTH devices or equivalents.

As Vic says, it's not clear what RAB is hoping to accomplish by "switching out" the Iota (a shore-powered battery charger and power converter) to a Blue Sea 7622 automatic charging relay (ACR). They serve two entirely different purposes. The Iota inputs 120 volt AC from shore power and exports 12 volts DC to charge the camper's house battery and power the camper's 12 systems (lights, water pump, refrigerator control panel, etc.). The ACR simply sits in the connection between the truck's battery and the camper battery to prevent one of those batteries from discharging the other.
In any event, the ACR wiring diagram <http://assets.bluese...ram/ML-ACRs.jpg> shows that the wire from the truck's starting battery connected through a fuse to Terminal B on the ACR; Terminal A on the ACR is connected through another fuse to the + pole of the battery.
Does that help?

@RAB, did you mean the Surepower 1314/1315?

You have the 7622 - Info here - https://www.bluesea....l_-_12V_DC_500A
Did you get the remote switch? If not, the wiring is much simpler than this diagram shows - http://assets.bluese...ram/ML-ACRs.jpg
Instructions here - http://assets.bluese...0180180-005.pdf
But, in answer to your question, yes. PLUS the small black wire goes to ground.

I did get the remote toggle switch. I haven't started the wiring, waiting for more parts and nicer weather. I'm not sure of the wiring for the remote switch. I may contact you later on that. Thanks for the help Vic.

Rich, that remote switch baffled me for a while too. I haven't added that part to my current build yet, but if travel plans are on hold because of covid, i could be tackling that again soon. Timely question.
Maybe we could get the mods to change the title of this thread to be more about "Replacing SurePower with BlueSea" or something like that?

The above discussion actually brings up another question I had between the differences in the Surepower 1314/1315 (I'm assuming to Stock 2008 FWC) wiring.
My Surepower was wired like this
-"Aux Battery" had a 10 AWG wire going to the IOTA and another going to the house(camper) battery
-"Main Battery" had a 10 AWG going to the plug, then to the truck battery/alternator
I've looked at the wiring diagrams and a lot of posts refer "to just kept wiring the same."
So mine is currently wired with Terminal A (to house distribution and to house battery-two separate wires) and Terminal B (truck). Anyone see a problem with this?

If I visualize this correctly:
1) the former "main battery" connector from the surepower is now "terminal b"... and heads off towards the truck and its alternator/batteries
2) the former "Aux battery" connector from the surepower is now "terminal a" ... and is connected to the +ve output of the IOTA charger and also to the +ve terminal on your camper battery.
Right?
Sounds fine to me. Odd to use the ACR/Surepower isolator as a terminal block that way. Not the way I would physically do it, but fine logically and in practice.
