I am still in need of some guidance in solving the non-functioning clutch on my Toro walk-behind mower. The engine is a Kawasaki FB460V-DS08. The circuit from the alternator is showing 30 volts AC. On the DC side of the rectifier I get 34 volts (DC). When I flip the switch to engage the blades the voltage drops to 4.5. I tried a different switch to no avail. I've already replaced the rectifier which had failed earlier testing. The clutch itself on the bench reacts fine to 12 volts and engages. My manual states that the clutch needs 11.9 volts DC,2.9 amps which should be attained when the engine revs to 3000 rpm.
