I have a 07 Sabre bought 11/07 I have no prior experience with onboard chargers, mine is the pro pak III, I was charging the batteries and banks 2&3 go green in just a few minutes and bank 1 stays red for hours without turning green. Is this normal? batteries are flooded cell continental that came with the boat. Will banks 2&3 shut off while #1 is charging? I finally got to get out on the water for a couple of hours, got home plugged it in and the same thing. John
