2086 HELP needed PLEASE!!

[pennsdalerepair]

I've got a 2086 that the PTO clutch will not engage. What I have done so far:

- fuse OK
- seat switches (N.O.) test OK
- interlock switch OK
- ign sw tests OK
- PTO clutch test OK for continuity
- Bosch relay not energizing--can get it to energize by running jumper from B+ to BROWN wire on relay plug
- voltage OK--12.5 VDC not running---14+VDC running
- reverse switch OK
- no critter chewing on harness
- no corrosion on terminals--
- PTO switch OK- even tried another known good switch--no change



All help appreciated!!!!

Sounds like it is time to get the schematic and meter out and do some trouble shooting.

I can help. (A) I can help you online, or (B) I can send you the Wiring Diagram and you can track it down. What would you like to do...???

BTW, welcome to OCC.............

I would unplug the PTO. With engine running and safety switches met. Turn on switch and see if your getting voltage to on wire close to the PTO. Whenever it comes to electrical use the divide and conquer method. If no power at PTO, check for incoming and output power from switch and so on and so forth.

Thanks, guys!! No voltage to the power lead to the PTO clutch. I "jumped" the brown wire leading into the relay directly to the battery+ and triggered the relay. I get 12 VDC into the PTO switch but nothing out when activated, leading me to believe a ground short or bad safety switch. BUT, checking the safety switches proves they function as they should. Thinking about ghost voltage; have to check that in the AM. the deeper I get with this thing the more frustrated I get!!!

Sounds strange. If you’re jumping 12 v positive to brown wire, that goes directly to the pto coil via the “rear pto jumper”. The coil is then grounded. When you jump the pos to it, is it then pulling in or no?

Edit: seems I was looking at the wrong schematic, 2084.

I think it is the relay, BTDT but check your grounds.

Here is the wiring diagram.

I know this isn't the right thing to do, but ran out of time chasing the problem. Needed the PTO to run the snowblower on my 3235 so I cut the (blue) wire that grounds the PTO, ran it to a toggle switch I duct taped to the cowl, and then a wire from the toggle to the negative battery terminal. Flip the switch, PTO gets grounded, blower starts blowing.....and I wasn't shoveling!

Smart move, necessity is the mudder of invention
Now you can take your time locating the problem/repairing at a non hurried pace.

Nothing wrong with a "field fix"!
