    Thanks Guys. Don't ask me how I know but if you connect wrong you get a loud bang, smoke, and oil dripping out of the thing.

    Wired it up. Flipped switches. No pop, smoke, oil, or smell. Good to go!

    What are they used for on a Kitfox?

    In our charging systems, the stator produces AC output which goes to the regulator/rectifier. The ouput of that is DC plus an AC voltage on top of it. A capacitor is often used to filter out higher frequency AC ripple on the rectified DC supply. It helps keep the electronics happy and audio quiet.

    Thanks, I was thinking to myself, there really cant be much on a kitfox that pulls enough power on start up that you to need the extra stored power of a capacitor but if it acts as a filter too that makes more sense.

    So how do you wire these things up, Do you run the hot wire to the positive side then continue from the positive side to the electronics buss? And ground side to ground, or does power go in one side and come out the other?
