You are a rock star! I spent a couple hours tracing the wiring on my 5045D, removed the ignition panel, removed the starter solenoid wire, disconnected the neutral safety switch, neutral relay and was getting nowhere with my meter. Came back inside and did a quick web search and found a few similar questions but nothing definitive. Then I found your video. It was everything it could be; short and to the point. I was so certain you had provided me with the answer that I went out in my pajamas, unplugged the thermostat sensor, tested with my 12 volt light tester (I'd already smoked 3 fuses), replaced the fuse and fired the tractor up. It did smoke a bit at first, but that has been happening for about two years so I guess that sensor had been going bad for a while. It took me a few minutes to put everything back together, but I did it with a smile because it runs! And now I can sleep tonight instead of thinking about what could be wrong. If you're ever on the West coast of Florida I would be happy to buy you several adult beverages! Thank you!
Let me join the fan club here and say that you also saved the day for us. Our JD 5045E mysteriously refused to turn over after trying to start it on a freezing morning last week. Battery was fine, but kept blowing starter relay fuses. Of course the troubleshooting guide in the manual is useless with handy suggestions like "no fuel" but no mention of the cold start advance sensor. Your video was all we needed, disconnected the sensor which was easy to find thanks to the video, put in another 10 amp fuse and it cranked right up. I found a new sensor on eBay for $15 and will install it when it shows up next week, thanks for the tip about the bucket to catch antifreeze leakage! In the meantime my wife's out cutting hay right now. Thanks again for posting this very helpful tutorial. 🙂
Thank you so much for posting this video. I have a John Deere 5055D kept blowing fuse and I tried everything replaced a diode after talking to a JD service Manager assured that was the problem. checked every safety switch. I had about given up. My tractor had been down for weeks and a friend came over and he just thought it was a wire melted or bare spot grounding out. searched many videos and none helped then I came across your video went out unpluged the sensor and it cranked . Thank you so very much.
OK, this video just saved me literally hundreds of dollars. I've spent several hours taking the starter off and having it tested (it was fine), searching the wiring for an abrasion or break (found nothing), spoke to 3 knowledgeable auto mechanics and one tractor mechanic, learned nothing except you have to "just search for the dead short, it's there somewhere". SIGH! I was getting myself ready to call the dealer, having them pick up the tractor, spend probably 1500 to 2000 dollars to have them find the issue. At my wits' end I did what I should have done first-searched for "blown starter relay fuse on John Deere 5055e". Because when I did I found your video. I went to the tractor, disconnected the cold start advance sensor, replaced the fuse, turned the key AND IT STARTED! I can't thank you enough, you're the best! Steve in Nova Scotia
Thanks so much for your video big help, my son-in-law has a John Deer 5055D exact same symptoms had been troubleshooting for hours started search and found your video absolutely the problem, changed blown fuse disconnected wiring harness to the sensor, and tractor started right up thank you so so much really appreciate your video. 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Thanks so much for posting this. My 5075e just had the same problem this morning. Found and swapped the blown fuse and it blew right away. Then i found your video, unplugged the sensor and it's working fine now. I can't imagine how much time and expense it would have taken to figure out what was blowing that fuse without you.
Your video just saved me time, money, and a whole lot of aggravation (putting it mildly)! I had the exact same problem. None of the professionals that I talked to (and I talked to several) ever suggested looking at the sensor as a possibility. As a side thought, I changed the coolant about a month earlier. Don't know if that played a role in the sensor going bad or not. Guess I'll never know. Thanks for saving my day!!!
This video just saved my arse! Customer has a 5093E, I was googling wiring schematics and happened to come across this video.. figured it can’t hurt to try, BAM problem solved! Thanks very much from North Queensland Australia!
I was scratching my head with the same problem and had a mechanic scheduled to come out when I saw your video. You solved the problem and made my day. Thank you
I work at a John Deere dealership as a service technician. That is the cold weather timing advance sensor, and is literally not needed in warm climates where it might get below 30 mabye 3 times a year. My best advice is to snip the wire, and tape the connector away because that sensor will go out again, and is not needed. The tractor will just take a little longer to crank when it is cold.
@@nathanschneider8586 upper left 30 amp fuse, I believe f101. it’s only when I try to crank. If I turn the key and then start by shorting the contacts on the starter, it starts and runs fine. I plan to isolate both ignition switch and starter solenoid today to rule them out individually. I also have the battery light on and gauges not working(alternator charging 14.4v) unless I remove fuse f113, then gauges work but battery light stays on. I’m not sure if that’s related or a separate issue.
Thanks. I have a 2007 5103 and it just shut off while idling yesterday. On my JD that fuse is labeled spare. It just kept blowing. Disconnected the thermostat sensor, replaced the fuse again, and started right up. Got me out of the field. I'll replace the sensor now that I know what was up. I appreciate the video!
I have the same year and 5103 also. Same exact thing. Went to drop a round bale in the field and it just died. I said I’d replace the sensor when I disconnected it, but that was 2 years ago. Maybe one of these days
Thank you for the info. I have a 2012 5101E and this fixed my tractor. You saved me a bunch of time. Fixed it for about $85:00. That's the sensor and 2 gallons of anti-freeze. Thank you so much for posting this.
Thanks. My 5055D tractor was doing the same. I did exactly what you said and it fixed my problem and I didn't have to pay someone to come out and fix it. Thanks for saving me a bunch of money.
Your procedure worked perfect on a 2011 5075e. Haven't ordered the new sensor yet but every step was perfect. Oh the fuses are mini's by the way. Thank you so very much!!
Thank you so much for making this video! Last evening my 5083e did just what your tractor did. I freaked out at first.. then I knew the answer would be somewhere in RU-vid land.. I have some serious mouths to feed.. thanks to finding the problem and then finding the right video. THANK YOU! They all got to eat! God bless you!
Don’t know if you still monitor comments on this video, but thank you so much for making it. I just bought a second hand 5083e got it home used it once and then wouldn’t start looked everywhere for an electrical fault and couldn’t find anything. Search up the YT and found your video, went out disconnected one of the sensor ports, tried to restart blew the fuse had another look and second sensor port disconnected that one reconnected the other and tractor starts. 🎉🙏🙏👍🏼🇦🇺
Like some others, I spent several hours troubleshooting my 5045D starter. After all, shouldn't the start relay be part of the starter circuit? Nope. I found when I pulled out the start relay inside of the fuse box, the start fuse would stop blowing but the tractor would then turn over but not start. Just when I was ready to give up I gave this tip a try. Sure enough, the tractor started right up! Saved me a big pain in the butt of loading up the tractor and taking it to a dealer,
Thank you for sharing. One of my most favorite neighbors has an issue with his 5075E but man it is stuck a mile or two in the woods on his property so wish me luck that this takes care of it!
After a whole day of trouble shooting my 5303 with no luck on the cause of no crank. I found your video. Can't thank you enough. Disconnected the sensor, replace the fuse and it cranked right up and saved the day because I really needed to use my tractor. Also, on my fuse block the middle fuse for the starter relay is labeled " spare", go figure.
Thanks for the video. Solved my problem. It appears this is a very common problem. Always a tip off when my John Deere dealer had several of the sensors in stock.
I'm blowing fuses and I do not want to have to go threw that bird's nest of wires in there all day long! I have put almost all new parts on this tractor (D140). Selenoid, battery, PTO switch, Key switch, Coils, plugs, gas filter, air filter, gas pump and a new PTO clutch. As well as eliminating all safety switch's. Oh yeah it has all new spindles on the deck! Last fall the blades stopped while mowing. At first I could get them on again but they would stop working after a few minutes and then it got to where I could not get them working and even had trouble starting the tractor. So I just put it away for winter and now I got this mess in the spring. I got it running with some of those new parts and battery.....but then after mowing three yards on my street I could not get it started after it sat for a while. And I found I was blowing fuses!
Thank you for the information. It is good to be aware of all the things that can go wrong with a tractor. We can save a lot of time and money . I appreciate your help thanks again.
Thank you !!!! We're fairly knew tractor owners and you just saved us some money. I just subscribe to your channel and hope to learn alit more from you .
A multi billion dollars company has its main machine broken, no one can fix it, then they decide to hire a specialist for a million dollars, he looks around flips a switch and the machine is fixed. The CEO asks: "Did I just paid you a million dollars to flip ONE switch?" "No, you paid me that to know which switch to flip."
Thanks For the Tip! I replace the ignition switch on my 2007 5203. Helped a litte but still blowing through fuses. Did you know that John Deer was charging 5 dollars per fuse! I was in a bind and I needed get my hay cut and Autozone or Walmart was out of the way. Now I I have figure out another Engineering Flaw on the Tracker. PTO handle looses after 4 hours turning off and on the PTO. I have to tighten after each day if not, IT will get so loose, the PTO will not turn on. Any help on that?
I have similar issue with JD5075E where 15 amp ignition fuse blows when you try and crank.... unfortunately pulling the temp sensor didn't help... open to suggestions.
Mine did the same thing. Just received my replacement via Amazon, while installing the insulation around the wires tore out where it goes into the sensor. Just applied epoxy to try to reinsulate everything. I have a feeling I will be going to John Deere to order another one later today. Cant complain about cheap China imitations because that's all John Deere is anymore, Made In China.
I'm not getting power to that system at all. I can jump the fuel shut selonoid from the battery and it will fire, but no power to and part of that wiring.
The sensor is for the cold start timing advance system to reduce smoke during start/warm-up so the engine passes emissions tests. It is useless unless you want to reduce engine life and startup smoke.
