I have a 48 inch scag walk behind with a 14hp kawasaki engine. the mower did not come with a wire harness so i bought all the hardware and put a new one on. Everything is hooked up but the electronic clutch still doesnt work, the blades wont engage. The clutch is good, i rigged the wires from another machine and the clutch worked. What could possibly be wrong? I also got a reading from the engine showing it is putting out amperage. any suggestions? thanks alot.
