Sorry about what happened to Josey Warren, I hope you've managed to get her in the vet's as soon as possible, I know it's worrying to yah. Thank you for the video.👍
I think it says a lot, when you go work on something you fixed year's ago. Some of your customer's have been with you for a long time, thanks for another well done video. God bless.
I always hated the automatic electric parking brakes on the JD backhoes as an operator on them. Too much "nanny state" type. Once again, excellent work diagnosing this and finding that needle in the haystack 👍. I had a similar situation with our dog last week. After being told no by 3 vet offices in a row, we finally got help at the emergency vet clinic and $750 later were back in action. Good luck with the pup.
I had to run a 710d 4x4 that every once in a while it would beep and the parking brake would slam on !!!!! wasn't bad when you were on site but when you were roading it somewhere and it did it she really scared the crap out of you!!!!
Good catch on the diode; they are widely used these days, across coils to suppress the reverse spike that happens when an actuator is de-energized. For fun, take any small coil, such as a 12v relay, (with no diode) hold the two coil pins between two fingers, and apply 12 volts. Nothing happens except the relay closes. Then, still holding the relay, disconnect the 12 volts. You will probably notice a nasty jolt, which is reverse emf. Big killer of ECUs Although only 12v went in, many times that will come out, which is the diode's job to intercept. Diodes used in this manner, when they fail, are easy to spot, as fuses blow when powering the actuator. Diodes are also used to isolate circuits in tricky setups like this parking brake Rube Goldberg invention. Much harder to solve and fix. I love watching you tackle the tough ones. Keep em coming.
I recall when a diesel engine had only one wire that switched it off and the handbrake was a lever on the floor. But that was to simple to leave. You are proving Warren that the modern "mechanic" has to have sound logic and electrical knowledge today.
Hi Warren, I had something like that happen to a puppy that jumped down from the kennel and got ran over by the other pups, he sounded like he broke his shoulder on a Saturday night, got it X-rayed on Sunday at a call-in clinic, nothing broken and figured out it was soft tissue damage with the radial nerve in the shoulder. Get some anti-inflammatories and pain relief, 2 weeks later he was back to normal raising hell with the other pups. The litter size was 16 rhodesian ridgebacks of pups. That was back in the mid-90's. I grew up horse farming and worked on many injuries with the racehorses, but it pulls on your heart strings when stuff like that happens to your pets in pain.
Josey is such a cute and funny pup, hope she is okay, glad she is going to the vet. I can tell how much you love them dog's, by how you talk to them, and always check that they haven't left for a joy run. When Josey cuddles up to you, i can tell she loves you. Them dog's are like having kid's, and they can pick up if something isn't right with you. God bless you and yours, please let us know what the vet says.
Diodes are the wonder of the electronics world (next to a transistor). They do wonderful things, but then you put them in heavy equipment, they are almost the last things guys check when it comes to issues. You thankfully know JD "loves diodes".. Nice catch Warren. Always great to find it before you start pulling plugs and measuring oil pressures and other more involved stuff. Hope Josey is just doing the "slow mend" from being mowed over by the other dog. Thanks for the Share, here's to Josey being OK and Stay Safe Sir! Thanks & Cheers!
Another, amongst many, of Master Class Diagnoses with the theory, the basics, and the and the practical, all being applied to net the best result possible. You have reset the expectations bar for the rest of the industry.
Thanks for the great information! I was a dumbass and replaced the parking switch and pressure sensor hoping that would be the issue. Wasted $100 bucks or so. It was the capacitor in the relay. The local auto parts store one and $39 for one I got two delivered for $10 from Amazon I’m going to use the relay is an antitheft device when I leave it on remote job sites since it’s definitely immobilizes the machine
Sorry to hear about Josey, if the vet had been open over the weekend Josey, you would already begining to heal, your Dad would have made sure of that.Another great video Warren, just imagine you would be back to a power probe, if you did not have the computer.
Hi Warren 😃 that was a puzzle mate, but you found it, although I was kind of lost when you were reading the diagnostics,old dogs and new tricks,lol . I sure hope Josie will be ok , she looks a bit flat just now, thanks for another interesting video, stay safe, best wishe's to you and your's, Stuart UK.
Diodes are known as electrical filters. Like Warren said they are kind of like check valves consisting of two parts, anode and a cathode, where alternating current can jump the anode but cant jump back from cathode thus converting AC current into DC current. The frequency of the chattering relay should match the RPM of the alternator because of the lack of a functioning AC filter. (diode)
@Chuck Kirchner Arranging multiple diodes can form a full-wave bridge rectifier. They are not technically called filters in a professional environment, but they do just that. They filter AC from the circuit.
I have the same machine with the exact same symptoms. Thankyou for walking me through that. Probing around with my meter, it was intermittent and nothing was making sense. I will check my diode.
Now you need to teach people how to use a DVM. There’s a ton of tech’s that have no idea how to use them. I’m from the old school, repaired alternators, starters, most anything that needs to be fixed. Great troubleshooting buddy!
that was a great tutorial on troubleshooting this issue. You assumed a starter, but not to be, upon further , you found the DIODE issue ! great tace/try/find !
Hope Josey is going to be ok Your friend in KY old retired CAT mechanic worked on coal stripmines KY SAM..love the AMTRACK train going by on your video..
The diode being a one-way gate fails in the closed position means a normal piece of wire in the loop. The diode put a stop on the feedback. Good vid Warren. Just shows that the little 'thing' could have you changing every component. 🙂
Warren the master diagnostic troubleshooter! How many ‘Certified Technicians’ would have changed the switch, the relay, and maybe even the starter and may not have even realized that it was the diode. There’s not too many guys left like you. I appreciate your videos and the work that you put into them. Thank you. John from Ontario, Canada- eh!!
Josey is so cute looking over your computer screen! If she is walking on it it's not broken! It probably got banged up good and will be a few days to feel better. Message it and see if it is tender anywhere, so you can show the vet! Better not to hang out with the big dogs!!
There are some motorcycles that have a hidden diode within the wiring harness. Those can fail too and cause all manner of problems. Owners often fire the parts cannon at the motorcycle and still the problem remains - the hidden diode (often taped over in the wiring bundle!) being the real problem. Must say it was a head bust finding that one Warren.
I have been following you for ages. This diagnosis you did just shows what excellent mechanic you are. Definitely unmatched on RU-vid! Great work. Keep up the good work and start adjusting your invoices accordingly (Ha ha)
That's a great road, I bet the rut's are a lot of fun in your truck, keep's you loose ya know. Poor old puppy, no doubt she'll learn from your empathy over time, lol, and keep clear of crazy big dogs. Great video
Hey Warren Had a 710g with those same symptoms it was two issues the relay and a hose leak for the fluid level and of course it was a hose along the bottom of the floor pan a pain in. The ass to get to but fixed and refill and no more issues. Symptoms were not wanting to move “in a angle “ or on fast take off crazy
funny that u said jd loves to stick them diodes in their machines. my little sub-compact tractor like 6 of them in the wiring harness. one blew a few yrs back that controlled the fuel pump, what a mess-finally had to break down and let jd fix it. a 6 dollar part caused me a lot of grief i''ll tell ya. thanks for the video!
Warren, from an old and sick man: As I get older my natural curiosity about things turns to people. I want to hear you talk about you. I know I am asking for something I have no right to.. Please tell me and I'm sure others, your story. Where did you grow up? Was your dad interested in the line you are in now?, where were you first introduced to mechanics?.. Where did you work? I remember vaguely you worked on a strawberry farm for 10 years and at some stage you were in the military? I will understand if you tell me, 'Mind your own business.' From a man fascinated by life, Caoe Town. South Africa.
I am sorry to hear about your furry kid Josey. Josey and you are in my prayer. Hope the vets finds out what the problem is and it not serious. I like say you and Josey are in my prayers. Greet Video.
Sorry to hear of the puppy's injury. Please give us a full report as soon as you get information from the veterinarian. Hopefully, just a minor muscle pull or something trivial this time.
Great video Warren really enjoy the way you show how to troubleshoot the problem and the fix. Hope when you get Josey to the vet they will get her feeling better stay safe.
Hope Josie is better Warren. I had to giggle when connection/switch "2B" became something to deal with. All I could think of was Hamlet and "To be or not to be...." Whether it conducteth electricity or not! 8-))
They started that electric activated park brake with the 310D .If you flipped the switch while the machine was moving it would snap the brake band inside the transaxle.Then you had to drop the transaxle ..Fixed every one we sold twice. Those deere engineers pulled some real boners over the years.
@@nathankisner8332 Diodes usually fail if you try to put power through them the wrong way. It was never a big problem when I worked on Deere (10 years ago) but they always get parts from the cheapest source.
Once again Warren you present a clinic on troubleshooting/problem solving, I really hope you don't have to endure "oh it was just a diode" (implying empirical reasoning on their part). While I doubt Josey is little more than banged up (most babies are very rubber like) it's a good idea to get the vet to look at her just to be sure, the last thing you need is to lose your tiny companion, it's obvious you two are fond of each other in the special way that only happens now and then.
In alternators they'll usually use a Zener Regulator Diode which allows current in both directions, but mostly only in one direction. It's like a limiting diode, so to speak. I believe they call it "avalanche current" in a Zener Diode? That most likely isn't the problem with what you have going on here though. Your situation looks like it calls for just a common one way only diode function.
My pup fell and broke her leg, they suggested surgery, but I didn’t have 6000.00 but the doc said since she was a pup they are resilient, they put on a brace/cast, she healed but with a slight angle because of the shattered bones and how they reheated, but she was good as new.
Anybody can pay for the program he has im sure. But it’s probably several hundred bucks a year, perhaps even per month, the reason it’s so expensive is so you take your car/farm equipment to a mechanic
You did good diodes are confusing when you do not have the big picture and can have quite a few functions but mainly as "anti ringing " on relay coils but also can be used as "steering" circuits similar to an array of check valves in hydraulic circuits. Not the easiest of fixes even for someone with an electrical background and could take "forever" without a schematic as you need to isolate individual components as you do not know where stuff is going!
Hey Warren! Where can I find those manuals you are using? I have Mitchell for trucks, but do you buy each individual manual? Or do you have a source for them in lots? I’m a truck mechanic but I want to get into more ag repair locally down here in Sacramento. Thanks! Your videos are always helpful, and we appreciate ya taking the time to make them.
Warren-Need your knowledge on a JD 6400. Had brakes de-laminate and contaminate hydroponics. Fixed that ok -then went into clean the rest of the stuff and replace all other disks in transmission? Tractor acts like it is forward and reverse at same time-getting ready to pull transmission back out. Electrical checks out ok- Can I get help from you- I am a paying customer.
Good video. I'm troubleshooting and repairing a 2004' John Deere 210LE. T0210LE884543 skiploader for free and donating my time. It belongs to a horse ranch that takes in neglected and abused horse. They get help by people donating to keep the ranch working. Anyway, would you happen to have the electrical schematic for the parking brake? Since I'm having the same problem you had on this video. Thanks.
