I have just purchased a new boat which is my first boat and have a 24 volt trolling motor with a 3 bank on board charger. Which gives me two banks for the trolling motor batteries and one bank for my cranking battery. When I get back from a trip I put my batteries on the charger and let them charge. The charger shows that the all batteries are charging. I can get my cranking battery to full charge and one of my trolling motor batteries charged. No mater how long I leave my batteries hooked up it will not charge the one trolling motor battery but says it is charging. I know the charger is not charging because when I hook a amp probe on it it is not drawing a current. Has anyone come across this problem before? Also, the batteries are new.
Thanks for the help
