[trkyhntr]

Quite possibly the most helpful video on the Internet for a john deere owner.

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. 🙂

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!

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.

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!

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.

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

[locketwt]

EXACTLY what happened to my 5303. Thank-you so much for leading me to the diagnostic answer and fix!!!

[TheFritz]

This was the only failure I have had on my 5520 in the last 20 years...thank goodness for YouTube.

[cowboyzr]

You just saved me a massive headache man lol
In a big hurry to move a downed tree, tractor wouldn’t crank. Thanks!

[robertlambert]

Thanks for the awesome video. Saved me lots of money and frustration

[WishslimesCo]

Having this problem today. Looked it up and watched your video. You just saved a large service call repair bill. Thanks so much!

[zacharylankford]

That worked to diagnose my 5103. Thank you.

[morelandclearing]

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.

[twodudesonepug]

Thanks man. My tractor had this exact issue. Started right up after I disconnected the sensor and replaced the fuse. Saved me $400!

[JimMcAnelly-elwn]

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!!!

[Iceracer-rbcg]

Thank you for the video! You're an absolute life saver. Mine quit in the middle of the roofing job and your video was 100% helpful

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.
