ATTENTION!!! 5000 series owners. (5M, 5E and the older 5XX5 series, and maybe others) "If you haven't had this problem yet, you will." And you need to know what to unplug so that you can start your tractor again.
EVEN if you've never heard of this, PLEASE read this thread. (You might even want to bookmark it) It will save you a big headache and a service call from the dealer.
I realize that I'm not the first with this problem, and certainly won't be the last. I wanted to post this thread for others that run into the same situation.
Here are the only three threads that I've been able to find on it here:

Earlier this year, I had a tractor mechanic at my farm working on the Blue tractors. New seals for the injector pump on the 2600, and new rockshaft seals on the TN70A. He looked at my two green tractors and said, "If you haven't had this problem yet, you will."
He showed me the two-wire plug on the injection pump, and said "when" (not if) it happens, unplug this and put a new fuse in it. He was right.
I didn't give it another thought until I tried to start the 5085M on Dec. 24th. It had been about a month since I ran it, and I wanted to let the battery charge for a few minutes while I loaded hay with one of the other tractors. I turned the key and nothing. No dash lights, no radio, nada. I thought, well the battery's dead. Went in the shop and grabbed my load tester, but the battery was fine. Now, I'm scratching my head. Then, before I could figure it out, it was lunch time. :licking:
After lunch, my brother did a web search on his phone and came up with one of the above threads. Then, it hit me. I remembered what the mechanic told me. Went back to the shed, unplugged the cold start advance, changed the fuse and all is good. Just for ref., the 5085M was bought new in '10 and has almost 900 hours on it.
In the first link above, TxJim posted:
What will it matter if I DON'T replace this sensor? Will my temp gauge still work? Will it crank fine in our winter weather? (Here, in LA, we bottom out around the low to mid 20's, and that's pretty rare)
Thanks again to everyone that makes this a great site. Hat's off to you.

I agree. I don't understand why JD just sweeps this under the rug. I've read that the sensor is about $50. Haven't tried to buy one yet, and don't know that I will. That brings me to a question.Being a former JD dealer service manager it's difficult for me to understand why JD hasn't corrected the temp sensor that's had a history of failing since the mid 90's when the 5000 series tractors were introduced.:confused3:
