Thanks guys for your input! I knew it came on at what I considered to be a high temp. I checked the fuse and pulled the led off the temp sensor and grounded it and it did not come on. So I will try batt direct to the fan and if it does not work I will get a replacement motor. I assume the lcl auto parts store could match it up. I typically do all my own work so I need to get a good shop manual, what do you guys recommend? I have 5 tractors ranging from 1940-1974 and I have shop manuals for all of them. My 900 only has 300hrs on it and so far no problems, hope it will stay that way.
Again, thanks for your help,
Ok guys, fan works(direct from batt). Does not work when grounding the lead off temp.
