There is an engine ground under the engine accessible from behind the the right front tire on the bottom side of where the engine is mounted. If you follow the wires from the back of the engine compartment, there is a hole that the wires run through. There is a bolt that the ground wire attaches to on the bottom side of the engine compartment. If this bolt gets loose, the ground is not completed and the electric clutch will not engage. Tighten the bolt and it should engage!! Problem solved.
