B&S Vanguard twin #303447 16 hp Engine

[sos1]

I need help with ignition switch. The engine has a red wire (alternator)that is not wired into the 5 prong wire plug.
There is a 6th prong on the switch. I connected it there but no luck. The engine cranks but won't start.
There is no spark. Help!!!!

Years ago I rebuild my Dad's B&S twin in his Gilson tractor. As I remember that installation (the manual went with the tractor when sold), the ignition switch is a part of the tractor and not the engine. That wire might just be a ground wire. Best I can say without photos. I put electronic ignition on the B&S and did away with a lot of spark issues.
