I have a Gravely 260Z. PTO switch failed so I ordered and installed a new one. It lasted about 3 hours and it failed. The common terminal on the PTO end of the switch is melted. Looked at a couple of videos on you tube and found the most common reason they fail is a shorted pto clutch. Clutch checks out at 2.2 ohms which I guess they are normal between 2 and 4 ohms. Any ideas what I am dealing with? Is it possible the clutch gets hot and then shorts out? Is there something else that could cause this? I don't want to buy another switch without fixing the problem. I see I can order a heavy duty 10amp switch so makes me think this might be a common problem.Thanks for any help!
