    I have an old motorcycle which will not run unless there is a battery. The battery is a 6 volt 5.5 amp/hour. I read online somewhere you could hook a capacitor in place of the battery.

    I tried hooking a big capacitor in place of the battery and it worked great for days. Kicking the kick starter, charges the capacitor and builds enough to fire the coil. Once it's running, it keeps charging the capacitor. One day I have no spark. My coil was not working. I later find out, the battery acts as a voltage regulator.

    I don't want a battery in there, because I don't want to maintain it, not to mention I don't want to be stranded somewhere.

    So the question is...
    I can measure volts much higher on the capacitor. Is there a way to regulate what comes off the capacitor to the coil/points so it only lets 6 volts? Thanks!

    Yes, no automotive modification discussions. There are other web sites for that.

    Won't work, since the moderators (of which I am one) are now aware. You really need to take it to one of the other recommended sites.

    The owners of All About Circuits has elected not to host discussions of automotive electrical system modifications/enhancements due to safety concerns, the potential of legal ramifications and the possible circumvention of vehicle regulations at the state and federal level.

    This thread is against the AAC forum rules, Chapter 6, as seen here:

    This can be found in our Terms of Service (ToS)
