Hi folks, glad to have found your forum, I've learned a lot and contributed a fair bit on Corvetteforum and HDforum. My 14 year old son saved his grass cutting money and he purchased a used Rupp Scrambler Trail 70 that we are working on. Runs great but we want to get the lights working. The horn works great, but none of the lights work. It's missing a battery, but using my multimeter the bike puts out 8 to 10 volts depending upon how high I rev it, testing on the horn leads and also on the battery leads. Are these Chinese clones 6 volt or 12 volt? The taillight uses an 1157 bulb which is 12 volt and the horn says 12v on it, but the 8-10 volt output would make me think it's a 6 volt system and the battery box is tiny to hold the old 6 volt batteries. Next project is to take the right handlebar control apart to see why none of the lights work. Any advice on this would be appreciated too. Edit: here is a video of the charging circuit in action, as well as the wiring in the headlight bucket. Appreciate any advice on anything that looks wrong. I have a set of controls on order as it's clear the headlight switch is busted.

Do they make a 12 volt battery this small??
