jd 110 tlb

[Wrenchin]

I have ajd110 was blowing hydro component fuse ,replaced HST CONTROLER solved fuse problem ? but indicator light to calibrate all potenteiometers will not show on dash ? I have 95% of harness hanging out of machine found it has 29 different grounds all splice to different colors and wier #s .I checked all volts to all potenteometers .,all ok jumped F-N-R solenoids wheels move tried new dash and another HST CONTROLER same thing /key switch to ;also checked all relays and safety switches .SHOULD I REPLACE THE HARNESS?????? this thing is driving me nuts .the dam thing only has 400 hours ,help of any kind would be awsome:confused2::mad

I wonder if the new HST controller needs to be calibrated?
Did some add all these grounds? Why would it need 29 grounds?
I'll bet a new harness is big $$$$$. I think I would spend my $$$ on a technical manual that has wiring diagrams and repair the harness.
It (tech manual) should also tell how to calibrate everything.
From what I read there is a fuse that has to be installed for calibration. BUT do NOT just install the fuse, it resets all calibrations to ZERO, NOT to default settings. Then you MUST recalibrate. Did you possibly put a fuse into the calibration slot?

 

[Wrenchin]

hay thanks for reply all the grounds are factory splices I have all test equipment and manuals ,when the fuse is put into calibration slot the service light on dash should come on and start calibration codes .it never comes on ,I have checked most components for shorts but you need pencil fingers to get to some of this crap .I have the jd full calibration kits for 95% of jd tractors all I can find is a bad ground that shorted to a hot becuz HST controller was fried upon cutting it open its almost like some one did some welding on machine and sent a massive jolt threw system but theirs no melted wires .do you think I should remove all HST SOLEINODS to all functions and test them? I work for JD as a tech but never seen this happen.

 

[Wrenchin]

machine starts bucket and backhoe work just wont move ,but unless that calibration light comes on to start code readings nothing can be calibrated I even tried forced calibration using PC NOTHING if any one out there has had this problem let me know. I even filed a case with JD and got less info than I know thay told me that was not a commin problem no ****.

There is nothing I can do to help, but I wish you the best. Is there anyway to go 'higher up' with help from JD?

 

[Wrenchin]

iam going to try and have them share the bill if I can find a fault in harness ? thanks you guys are great love this fourm, I will be sure to reply all I find once this thing is up and going thanks to evry one .

I'm not very familiar with Deere in general... I do own a 110 TLB.

Last year I had a problem with the flywheel sensor which made the forward and reverse pedals unresponsive... I was able to limp back to the shed with the creep function.

My heart sank thinking of all the things it could be and it was Christmas and my Birthday all in one when it turned out to be a $65 sensor held on with one bolt.

Just putting this out there...

Here's a link with picture and part number

You don't mention testing the light itself. Could the bulb be burned out? The light should come on for about 4 seconds each time the key is turned on.

 

[Wrenchin]

yes I did check that to I jumped power to all dash operations all worked just talked with JD rep today going to send me anew harness for half the price because of the low hours it has they told me this is a first one that this has happened ,with no melted wires ,they also told me to replace all spool valve soleinods that have to do with hst they make it sound easy ,like I said before you need pencil fingers , but I have gone this far so im going to remove cab.thanks for reply :confused2:

 

[jenkinsph]

Good luck with finding the problem, seems like a lot of parts being changed and doubt they all needed changing.

 

[Wrenchin]

jenkinsph I agree with you 110% its bull crap that JD wont give me a positive answer they don't seem to want to help just change this and that ,but don't seem to care about how much work this is like:banghead:thank you .

 

[disney]

Evening. You have most likely done this but.... what if you disconnect all of the solenoids (or what ever might be causing issue), and then reconnect them one at a time while attempting to move machine (or perform calibration) after each reconnect. I know basically zero about the system, so I feel there is little intelligent help I can offer

 

[Wrenchin]

funny you mentioned that's what iam doing tomorrow ,hope to get some kind off reading on PC ,its just frustrating because potentiometers for F- N -R throttle position inching lever in TOT ,BOT are reading proper volts when I test them with JD volt meter kit but PC CANT so all I can do for now is what you and I were thinking ,JD has to make harness not a stock item ,thanks you guys are great love this sit:drink:

 

[disney]

another thought I had was you stated you tried another cluster and hst controller, but did you try them both at the same time? I only ask b/c what if the issue is in the cluster, and the cluster 'took out' the 1st hst?

 

[Wrenchin]

yes I tried that, the older cluster did not seem bad ,no burnt smell anyway . I had made a sires of plugs from left over wierin harnesses to use as testers all functions worked ,thanks :stirthepot:ill keep at it tough I don't give up till I find and fix,iam the guy in the shop when it looks bad and has all others scratching heads it all ways comes my way

 

[jenkinsph]

I don't think I would change the wiring harness on a whim. I would work backwards from the light bulb to see if I could find the problem. I would also wan't to verify that all signals were present for forward/reverse travel as it sounds like you are missing a link here.

I had a problem with my 4520 soon after I bought it, lost the program and wouldn't move. Deere dealer reprogrammed it and it worked for another two years without incident. The problem came up again though when I was rototilling some hard ground and shaking the tractor. Turned out to be a poor connection on the computer bonding strap to frame, that fixed it works fine after another couple of years. I have since shook the crap out of it several times to make sure it is fixed.

My point being make sure all the connections are making good contact. The harness itself if it has a problem can be fixed but I doubt there is a need for complete change out.

 

[Wrenchin]

jenkinsph I agree with you 100% I have tested all values to forward /reverse throttle ,inching lever ex... I did start from connector at cluster for code lamp the thing is it splices 29 different ways to a seires of grounds that go to all HST components I have it narrowed down to 6 wires but have to re move floor board ,it has an after market cab I was told today that this problem came shortly after this installation ,the machine is not mine it belongs to a customer who is not happy.this is it 3rd HST CONTROLER with only 400 hours ,I just started working at this dealer last year ,but from what I have seen lots of swopping parts hoping it works .I don't work that way but suck cuz I don't call the shots I checked volts from those 6 weirs 2 are suppose to send 5volt refrience to HST controller and their is nothing iam getting closer to the problem but have to remove all kinds of crap. but at least its getting closer.if new harness comes before I can find problem at least its all apart .I checked straps all over like you said;good thing I get posts to my phone its great having you guys handy but now that I know about cab deal I have a few more places to serch for pinched /crushed weirs some of the HST HARNESS run under /threw /behind ROPS its the work and time that's the killer I even work on it during lunch brake ,MUST FIND PROBLEM just for the fact that some one screwed up,but no one says a dam thing.thanks again for all the help you guys are good folk.:drink:

Wrenchin,
I have a Laurin cab I installed on my 110 when new back in 2005. IIRC, there is one ignition wire that hots up a relay for a 30 to 40A circuit that is connected to the battery positive terminal. There isn't anything else besides a ground strap tied into the tractor electricals that I can remember.

Good luck with the battle.
