What battery charger for e350 diesel with bluesea 7622 acr?
I own a ford e350 diesel and have installed a bluesea 7622 automatic charging relay. I have two starting batteries hanging from the frame which are connected to the automatic charging relay (acr) and the acr is connected to the house battery. The van is spending a lot of time in the garage this winter and I'd like to keep the batteries charged while the van is sitting in the garage.
Does anyone have a suggestion as to what type of battery charger I should buy and how to hook it up? All three batteries are hanging from the bottom of the frame and difficult to access so I'd like to hook the positive wire to one terminal of the acr and the negative to the frame. My guess is that the battery charger will open the acr and charge all three batteries when it is putting out a strong charge, but when the charger drops down to a trickle the acr will close and charge either the starting batteries or the house batteries, but not both. Thanks!
