The PTO fuse melted on my X304, and damaged the fuse block. I purchased a used X304 wiring harness. Installed it, and still no power to my Clutch. Checked continuity on the PTO switch, and checked out O.K. I purchased a new switch and installed it anyway.Checked the feed to the clutch with machine running. No 12volt power to clutch. I pulled the fuse for the PTO, and machine shut down. Looking for some help.
