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.

[font "Comic Sans MS"][#800000]I cannot answer your questions, but if it were me, I would find the nearest Interstate service center and take it all to them for a thorough analysis of your setup and recommendations as to how to proceed from there. If the battery was at fault, they will make good on a replacement.[/#800000][/font]

Not sure of your exact setup but---
My boat has a 12v - 24v front troller, a switch changes the voltage to the electric motor. When charging that switch must be in the 12v position for both batteries to charge. If left in the 24v position when charging only one of my batteries charges.
