2 bank battery charger acting weird
I have a typical setup with bank1 as the engine battery and bank2 serving the house. Problem is that when plugged into shore power and using the charger bank1 voltage never drops below 14 volts. Bank2 drops to 13.1 volts as expected after a few hours though.
Could it be how I am hooked up ? I have taken the positive leads for bank1 and bank2 to the 1/2/both switch - assuming the current will flow thru the large red wires connecting the batteries to the 1/2/both switch. However, I do run the negative cables for bank1 and bank2 from the charger directly to the batteries. Does this sound reasonable?
Thanks for any ideas
