That is what I love about being a heavy equipment technician for 38 years is that you never stop learning new things. Like Chris said a scope would be indispensable. Great job with the videos Warren.

I'm a fairly new tech on tractors and I just got a work order for a 6300 with the same issue, this video helped me out a lot! My issue was 1, previous tech wasn't interested in trying, and 2, rocker had a bad potentiometer

Happy Anniversary to you both.

I wrench and fix all day. But Warren I love learning. Thank you

Hi Warren. One tool I've found indispensable for these head scratchers is an oscilloscope to check the PWM signals out of modules. Had a 6410 that was being weird and not changing the rate of drop. Potentiometer voltage changed, stepper motor worked good manually. Hooked the scope up and could see the pulse never changed regardless of the potentiometer position. A calibration solved it but it was nice to get a view of what was going on. Not many OEM troubleshooting methods mention scopes, and not sure why.

Thanks Warren love your work

Thank God people like Warren like to tinker and fix stuff. Because its complete bull crap how complicated a damn tractor has become. Warren, your worth every penny you charge.

Thanks for sharing, Happy Anniversary 🍻

Congrats man, your vids are very useful, pro tools and knowledge. I have a 6200 with same problem i hope i can fix it thanks to this video.

Great vidio Warren. I really enjoy watching them. On a side note it might be easier for you to use the arrow keys on the laptop to go up and down on the pages. It might be easier than trying to use the mouse pad all the time. Just a suggestion for you. I used them quite a lot in the work I did.

Great work Warren thanks for sharing but ( don’t be late for your date )

If I ever heard the rest of that submariner's limerick I'm pretty sure I could never think of Grandma in the same way ever again. So I'm kinda glad you stopped where you did. : )

Thanks for sharing. Enjoyed the video.

Love the videos if i lived in California i would help you with all your work

Be nice to that Deere the 6000 series is used for almost everything over here in Europe

Be safe thanks for sharing God bless

I have an auto shop and most people think that plugging in an "Scan tool" tells you what the problem is. Well it is nothing more than a tool in which will help guide you to diagnosing issues. As you well know a code does nto mean a bad part.

Can you give me the site you use to look step by step to calibrate the arm ?

How do you pull codes on an early 6300? I can't see anywhere to hook up to it? We've got an unresponsive hitch control but it works good with the manual screw.

pulse width modulation to control stepper

what that thing on the rear is?, what ge is doing?, i have problem lifting it up, i think i have that thing dead

Does anyone have an EEPROM dump for an AL81198 HCU? or sometime close. The HCU became unresponsive during calibration.

In the dog house!:-)

Who makes that new little computer for $800.00 - can you use that on all brands

This is Why my dad and i don't own anly John deeres

I thought you could get to the addresses and calibration through the tractor cluster ... or you need that performance monitor

I thought 'ONLY' JD dealers can work on the new tractors they sell !

Your going to have problems with your laptop if you don't keep that dust away from it { just saying }
