Hey guys I'm having a couple issues with this same unit. My serial # A801N06673U. My machine has no travel and no steering but it does go up and down. A couple things I noticed when I turn on the key switch the power contactor kicks on but the electric brake kicks on for one second and then kicks off. I have checked all the fuses. I do not have a manual for the truck. I would appreciate any help that will help me troubleshoot this machine. Thanks in advance Rick

hey guys still trying to troubleshoot my steering issue update i now have travel and lift still no steering i have power to my steering tach and to the steering motor itself but no movement i see fluxuation in power when i turn left and right at the steering tach and at the steering motor is there a way to test my steering motor like a bypass or a straight wire to see if it is my problem thanks in advance

Ok so now I have no error codes brake switch was faulty but was replaced now I am set with no steering I can hear the steering tach pulsing but have no power to the steering gear (has the chain) thank you for all your help btw

Ok steer tach ohms and I have now error light3 I do not have to power to the drive gear that has the steering chain

Steer tach is behind the steering wheel. Steer pot is down by the motor and controls. ECM is by the steering motor. All your test taps are by or on the controller.

please excuse me for my ignorance but I'm new to this machine and not to sure of location of these areas you are describing

Check the following.

Open circuit in between tach and ECM or between feedback pot and ECM

Defective tach

No output from ECM to steer motor

Feedback pot defect

Check tach input. Test voltage between K1-4 and TP3 when tach is spun. Test voltage between K1-6 and TP3 when tach is spun. If voltage present then bad ECM.

Master drive unit out of range. Jack up truck and turn drive unit back into range.

Defective steer motor

I have a Yale oso30ean24te101 and have lost all steering has travel and hydro I'm at a loss and am hopeful to get somewhere here please any help would be great also have error lights 3-4-5

Without a manual I am flying blind here. Possible to get calibration procedure ? Thanks. Never mind I just read the warning on sharing any copywriter material

You need to calibrate the steer center setting to stop it from drifting off center providing the tach generator is not generating noise in the left turn circuit causing it to drift.
There is a calibration routine in the steering section of the manual for this and other steering functions.
One other thing you may want to check is the hour meter display on the BDI meter and see if it is displaying any codes when it is driving in slow mode.

I'm having steering issue with same model. Slow response and motor creeps left with hand off tiller

check the pot and make sure it reads good, no hot spots in the readings, any glitch can trigger a fault.
also check real close the helical connector that connects the pot to the steering gear (if it is older style), they have been known to break , if newer style then the pot inserts directly into the gear, make sure the set screws are tight.

once you confirm the above conditions are satisfactory then run the steering calibration test in the information kevin sent you.

have fun ;o)

email is now in profile.

Thanks

Drive unit potentiometer out of range......
Pot needs adjusted,there is a procedure,have an email to put in your profile?????
