ok guys a little update. I went ahead and ordered a new cluster to fix this issue but then between Thanksgiving, vacations, bad weather and junk I couldn't get around to pulling the steering wheel and replacing it.
Today I decided to get out there and the darn thing turned over lol. Battery was a little tired so I hooked up a charge to it for a little bit and sure enough it finally fired up after a few cranks.. purring like it never had an issue now. Just ran for about 15 minutes and stopped and started it about 5 times to see if I could get it to not start but it starts every time.
So besides just leaving it alone for a couple months in the weather one big difference is today its a chilly and wet 50 degrees and back when it wasn't working it was 90 degrees and hot..
Would this have something to do with the thermistor?
I'm happy my deere is working but its too dang muddy to do any work lol. I'm going to start it daily and see if I can reproduce, trying to decide if I should return the $337 cluster or just replace it.
LCD with hours is working on mine, but I did notice the green left turn light is slightly illuminated on the panel at all times, so something is squirrelly with it.
