Hello. I am using a large capacitor instead of a battery in a 12 v motorcycle charging system. The recommended capacitor http://www.trailtech.net/040-CAP27.html appears to have a polarity. Can I use an AC motor starting capacitor instead and do they also have a polarity? I was not aware that there was any difference between an AC and DC capacitor or does an AC capacitor just have a diode built in?
Thank you.
Thank you.
