switched the connectors around like you suggested. it now throws code 32-40 lift handle not calibrated. i tried several times to run the calibration where you tilt both controls inward full, then key on, the press operate button. the solenoids are supposed to activate but do not run thru the calibration cycle. i would of thought the right control now hooked to the lift solenoid, and the left control now hooked to the right curl solenoid should have raised the bucket with the right control. the left control now plugged to the curl solenoid should have curled the bucket if the solenoid was good. does it look like the curl solenoid or valve is bad?? i did unplug the battery for an hour to try and clear the computer, but it did not clear the codes.
 
Given what it did before, and what it's doing now with the controller swapped, I'd almost guarantee that the solenoid/valve actuator on the curl circuit is bad.

I say this because you know the controller for the lift circuit works, because it was doing so when hooked to the lift solenoid/actuator. Now, with it hooked to the tilt circuit its not even calibrating to the solenoid/actuator.

I don't know how much trouble it would be, but to be 100% sure, you could swap the solenoid/actuator from the lift valve to the tilt valve, and run it with the tilt controller. If it worked that way, it would show definitively that the solenoid/actuator was the problem as opposed to anything else.

The bad thing with problems like this is that even the Mfgs know that when it comes to all of this electronic crap, often swapping parts is the ONLY way to troubleshoot a problem. I know Komatsu used to be, or should I say, is, good at running you to a point on a troubleshooting flow chart, and then saying, 'replace with known good part'. It then asks if the problem is fixed before going any further.....Funny thing is I asked an engineer at Komatsu about this on time, and he denied they do it....... I guess the guys that design this stuff don't bother to read the manuals telling you how to work on the stuff they designed...LOL

Good luck and holler back, I'm curious now....
 
i ordered a new actuator from bobcat, and the oring and spacer. should be in tomorrow noon. when i get er installed , i'll let ya know what happens. thanks for all your help!!!!! much appreciated!!!
 
Hopefully that fixes the problem. When you get that one, come on over and help me with a Deere skidsteer I've got to check on again. About two years ago it wouldn't actuate the implement circuit. First indications were the seat belt switch, since jiggling the switch seemed to make it work. So, it was replaced with no results.

By the time all was said and done I'd eliminated both the seatbelt switch and the seat switch from the equation, and it appeared the display (which housed the computer) was bad. So, nearly $700 later we had a new one. Swapped it and it still didn't work.

The customer finally asked me if I could just bypass all the crap and make it work. So, I proceeded to get a diagram from Deere so I could do as he asked.

When I went back to work on it.....it worked......Just out of curiosity I put the old display/computer back, and it continued to work.

I told the guy that I wasn't going to say I had fixed it, but that it was working. I hate making a 'repair' like that, when something just starts working again, and I have no clue why.

It's worked for two seasons now, but he called the other day and it's up to it's old antics again..........I wonder what I won't find this time....LOL
