I have a 2005 club car precedent that is not charging . The charger clicks after being plugged in but needle does not move. I tested the charger on another cart and the charger works fine on his. I was told to replace the OBC and did replace it with no resolution to the problem . I am getting 45 volts when I check the batteries and when I check them seperate I'm getting 11.4 volts . So any ideas what else it could be?
