    not charging properly

    i have also heard that putting in nylon screws to hold on the plate with the brushes will reverse the polarity as well

    not charging properly

    the wires look fine. still trying to get the right screw out to check behind the brushes. the brown wire, the return to the batt is reading the same volts as the batt itself, 11 volts, cause its not charging. but the green is still reading 1 volt

    not charging properly

    Sorry guys. Been on the road the last couple weeks. I just tried to locate the harness to stick the probe into and none of them seem to have with the same amount or different color wires. I think it's located directly behind the tank under the seat correct?
