Hi Brock, thanks for the Manual, got an index by ay chance? I found the ater 95 circuit (Chap 17) first I must explain that the engine is not in a bike but my Trike, I have only recently done an engine swap and only connected the heavy wire to the battery, all by trike power comes off the battery and then to the Trike ignition switch, I left the thin wire Bi disconnected but I see from the circuit it is in the charge circuit and will not charge if disconnected, correct? Joe.
