Putting E start on 69 45" trike. Rebuilt starter motor and so it is good. Wired it up on tranny with clutch and all parts. Have it sitting on a stand all wired up. Every thing engages and spins, plenty of battery. Watching the Pinion gear, when it engages clutch ring, the pinion does not trun clutch ring. Got a new one and it is doing the same thing, not spinning the clutch ring. What am I not doing????
