TYM T503 cab tractor - electronic PTO

[JFahey]

Was working fine then it just quit turning. Took the dash apart to expose all the wires and quick connects. No idea what I moved...but it started working. Used it for a half hour, quit again. Banged on the fuse box and wiggled all the wires and the main wire harness and it started working again. Worked for 10 minutes then that was it. No matter what I move around now it won't make connection. Is there a common place to find a bad connection that will make and break? Any input is appreciated.

Without it you are chasing butterflies: Get a service manual with a wiring diagram. Just went through some electrical problems down in the Branson section with a guy and without a WD no way would he have found his problem. You didn't post it in your line up nor say, what year is it and where do you live and where do you keep it......how do you use it. Connector corrosion can always be a problem requiring you to make/break connections sometimes to shine up the contacts, especially in"sensor circuits" where the current is low and any resistance in the connection impedes performance.

Tractor is a 2009 with 585 hours. Bought it 6 months ago and have only put about 10hrs on it pushing snow around in Western New York. First owner really only used it as a loader tractor cleaning out stalls. I pulled the fuse box out and it’s clean and dry. Doesn’t look like anything under the dash ever got moisture on it. There’s an almost unreadable wiring diagram in the owners manual. With it running, I have 13v at the PTO push botton but only 4 or 5 volts at the PTO switch.
