The thread re shore charger not working on gennie raised a question for me.
I have a ProMariner 1250 C3 charger installed and doing some batty bank reconfiguring.
Previously I had 3 banks plus a gen start batty
I'm combining 2 previous banks into one and moving my single engine start over to the thruster bank.
Previously I used the PM 1250 C3 to charge the 2 house banks and thruster bank. I had installed a cross-over Sw that allowed me to combine the house & gen just in case either one was weak and needed a boost. I could also combine to use the PM C3 to top off the gen batty occasionally.
Now that I'd only have 2 batty banks my plan was to hook up the gen to the 3rd charging position.
My question is...
Will running the gen and its alt providing charge to the gen batty signal the PM 1250 C3 to go to float?
I guess I dont know how a 3 bank charger works when one or more banks need charging but other(s) do not?
Does it always sense the weakest bank and charge to its needs?
Or is it controlled by a primary (#1) bank and the others just get less amp flow due to their condition?
If so, is there a chance of over charging especially if the bank size is significantly different?
I'd certainly be comfortable using only 2 banks and letting the gen alt take care of it's own batty charging, especially w the combine SW as a back up. I'd like to optimize charging performance for the larger and more expensive house bank.
