I have a minn kota 24v powerdrive and my batteries are Interstate deep cycles and an on board charger, boat was brand new in May last year. I plugged in the charger and only one battery will charge. After further investigating one of the batteries has reversed polarity and will not charge. Is this a common problem? I beleive the battery charger is a guest 2 bank, does it have a history of having a bad side that would quit charging the battery and cause the battery to reverse polarity. Thanks for any info you share.
