I have a 5 hp Briggs fun power with electric start. it has the single wire with red connector. from what I have found, the wire is 1.2 amp unregulated DC. What I am trying to figure out is: Can I run this straight to the battery to charge or do I need a regulator or what?? Also: what would b the smallest battery I can use on my mini bike to run the starter and lights?? I was thinking a 5L-BS? my engine code is: 136217-1140-E1 of it helps anything. THANKS in advance!
