Blade Clutch Won't Engage On Zero Turn

[Frogholler]

The blade/PTO clutch won't engage. I've checked the connector on the PTO switch and there's a lot of corrosion on two contacts. Next step is to try jumping across those two wires with the switch in the on position.
Does anyone know where I can view a schematic of the mower and the PTO switch?

Will need the model and serial information off the Zero turn before we can help you.
