6610 power reverser problem

[Blacksheep IT]

Had a problem whit my jd some days ago:

My tractor's power reverser after few seconds is disengaged on neutral position.
I got lot of errors on rcu diagnosis:
027
057
045
055
056
052
040
031
end
I think it would be better to clear errors and repeat test but I don't know how to clear it.
I checked fuses and relays and are all good.
park sensor is working good...

Thanks to who want to help me.

UPDATE : cleared RCU error codes by clicking on / off hazard switch while rcu diagnosis showing errors.

Started tractor and tried to go forward and backward, after 30 seconds power reverser disengaged to neutral position.

Checked again RCU errors and got only one error:
031

031 = Fault in enable solenoid circuit
Possible causes:
1) Short in enable solenoid circuit
2) Short in forward OR reverse solenoid circuit
3) Break in the circuit connecting components together

While fault is present enable solenoid remains closed and detent solenoid is off. Tractor wont move.

Thank you for the reply zebra,

Now what I should do to find where is the short?
I think the issue isn't a broken wire cause the tractor sometimes move for some meters.

Are the solenoids those in the photo?

I'm just curious. I replaced the low hours syncro transmission in our 6200 with a power quad 16/16 and left hand reverser. Would this transmission be basically the same transmission you have less the updated computers and electronics?

NEW UPDATE:
I checked some wirings.
The connection of the cable under the cab that goes to solenoids had a worn wire (grey one), isolated and tried diagnosis: same error 031.

Checked with tester ohm meter the couples of wires that go from connector to solenoids: there aren't broken wires.

Checked solinoids and had continuity on all but fwd and bwd ones had 11.2 ohm and enable solinoid (grey and black wires) had 4.5 ohm.

PROBLEM SOLVED!!!

After verification of enable solinoid I changed it and the tractor goes well. :thumbsup:

Thanks Zebra for your indications given on this thread and on "JD 6410,238 hrs,power reverser not working".

Now I need to have a shower! :laughing:

If fuses are not blowing, there should not be a short. Maybe a break in the wire that does not allow current to flow? Or partial break?
Do you have power to the enable solenoid? If not, you need to determine why. If you do, then maybe a bad solenoid. You could swap with forward or reverse solenoid with the enable solenoid and then if it move on only one direction the enable solenoid was bad. Different ohm reading makes me think it might be a bad solenoid. I think they are all the same part number?

Also did someone put a fuse in F115 diagnostics? Tractor will not move with that fuse installed.

Gray wire is enable solenoid
Lt Blue is Forward solenoid
Lt Purple is reverse solenoid

You must have replied while was making my last reply. Glad it's fixed!

Thank you again Zebra for sharing your knowledge.

I also have some oil leaks to fix, maybe I will do it tomorrow but...this is another story.
