X595 PTO will not engage for Mower

Hi There!
X595 PTO will not engage. Checked Module/key switch, relays, PTO Switch, Seat Switch, Brake Switch, over heat sensor and PTO Solenoid All Checked Good. I was mowing on hot day and mower deck stopped due to heat I thought. When cooled would not engage. I have gotten a couple momentary engagements but just a second or two. Nothing since. When I checked the relays you are supposed to get continuity between A&B and C&D. I checked the relay and did not have continuity between C&D. Thought I had it until I check the other two relays. They checked the same. Hardly a coincidence all three would do the same thing. Anybody have any thoughts on the relays? Or Any ideas on the whole issue?

Thanks!

Is there a spare relay that can be switched out with the suspect one?

No I dont have a spare but will get one Monday. It has to be either the relay or the Module/Key Switch Asm. It's hard for me to believe all three relays tested bad. Everything else works on the tractor. Not sure the Service manual has the tests of these relays correct. Any body have any experience testing these things.

Thanks for the reply!!

I finally figured this one out. All the relays were good. I was testing with a sound tester instead of Ohms. Each relay has a resister or something between C&D so all were good after I did it correctly. So bottom line thought I lost another Module but refused to give in. I undid the main wire harness and traced it throughout the entire tractor. Since this was an issue before I thought possibly another area went bad. Sure enough on top of the engine right above the thermostat the harness rubbed through and grounded out. Interesting part these wires went to the alternator so not sure the connection to the PTO. Possibly caused the relay in the module to act up. But after a repair and reroute, I put everything back together and runs like new. Thanks for the response.
