I am trying to find out how to eliminate the battery on a small displacement pit bike (mini bike) so as to be able to use the head lite etc. without the maitenance of a 6v battery. Will a capacitor do the job and if so what capacity would be best for a headlite, tail lite, 2 instrument lites and an occasional small horn. Usually there would be no load at all except for the possibility of a brake lite. The original systym was set up to carry these items with the 6v battery. Thanks ! ken
