Ok guys idk if I'm posting in the right section or not. But I got a question about a kart in building. (You can see my thread in the project section) anyways I'm rebuilding a manco dingo deuce and I am gonna use the predator 420cc engine with electric start. Can somebody explain to me the charging system. I'm running the original lights that were on it. But me being a 36 year old bass head lol. I was wondering if this system would Handel my lights and an after market radio with two speakers or should i run another battery and if so could I just use a battery isolating relay and can the engines charging system Handel it? Any ideas would be usefull. I'm just looking for suggestions and advice thanks in advance.
