IMO I would ditch that separator.
They shouldn't get that hot.
That could be a danger.
That's why the SurePower co recalled them.

You can use either the ML or the SL version. I have one I'm selling if you are interested. Some where in this thread I think I posted the differences.Wallowa said:What is the exact model of Blue Sea ML-ACR that should be used in our FWC?

Outnabout said:I think I know why the separator was hot when the truck wasn’t running. Interested in what others think.
I had the trickle charger on the truck batteries while the camper was connected. I think this pushed the truck batteries up in voltage to trigger the separator. I understand they get warm/hot when they click on. Charging the truck batteries seems to be the same as driving when the alternator is pushing up the voltage.
Outnabout said:Story continues. Truck parked connected to camper. Solar charging and separator hot. Volt meter in truck battery shows 14v, same as camper. Disconnect camper from truck and truck voltage drops. Seems that the separator is allowing solar charging to the truck battery which most likely is also causing the heat. If this the case then it seems like the separator has gone bad. My understanding is the power should only come from the truck.
Was the trickle charger still connected to the truck battery (and plugged in) when you did those last two voltage checks?Outnabout said:Checked voltage at camper to truck plug. Power at the plug from camper is 13.xx depending on solar charge at the moment. Seems as though power is flowing through separator back to the truck. I assume this would indicate separator is not working.
No, trickle charge was not on for the last checks I made.Old Crow said:Was the trickle charger still connected to the truck battery (and plugged in) when you did those last two voltage checks?
FWC currently uses Blue Sea Systems ACR 7611 in the factory build. I contacted them today and found this out.Wallowa said:OK .... Blue Sea shows the 12v ML/ACR in two models....7622 with manual switch and 7620 without that switch...which is preferred in the FWC and why?
Thanks...Phil
I think it will work for me. I don’t require much power. Lights, furnace fan, and eventually a compressor fridge.Wallowa said:Oh great...an ACR 7611? I see it handles less amperage and costs less that the ML/ACRs but is it the best choice?
And yes, I do have a winch, but of course only use it with Tundra motor running.
Best option?
Thanks...Phil
The switch model gives you the ability to turn it off/on remotely. I had mine in the cab of the truck along with some gauges when I had my Hawk/Gasser truck. Still have the 7622 and gauges in my box of parts that may eventually get installed again.Wallowa said:Oh great...an ACR 7611?

Outnabout said:Replaced the Surepower 1314A with the Blue Sea 7611. It was a simple disconnect old and connect new. I did have move the fuse that was already there for a better fit. Now the truck batteries can get solar charge from the camper, which is great because sometimes the truck sits for awhile. The other plus is the new Blue Sea is not a solenoid so it won’t run hot which is what the Surepower did. Thanks for the feedback while I went about the solution for my problem.
I want to say no. I think when I was researching the the ML was magnetic.Wallowa said:Is the BS 7611 magnetically switched? can't see on BS website if it is....
Has anyone installed the 7622 in the Surepower 1311A FWC location? Any issues?
Thanks...Phil
Yes the 7611 it is magnetically switched (all mechanical relays are) but it is not 'latching' like the 7622 and requires a small amount of current (~100 mA) to to keep the relay engaged when the batteries are combined.Wallowa said:Is the BS 7611 magnetically switched? can't see on BS website if it is....
