Evening all, Deere ct332 last 6# of vin 117549. Trying to find an electrical schematic or and idea where to look for loss of power to the electric cooling fan on the ac condenser. If I unplug it and jump power to it, it kicks right on. But tested pig tail coming from machine and no juice. Pretty sure that fan always kicked in soon as the key is turned on. Tried turning on the ac switch in the
Cab in case they were inter connected some how but still nothing. Any help would be greatly appreciated.

Without a schematic, all you can do, is look for a temperature switch, might be bad. Might be in the fan base.

Guys i want to thank you for the help especially mg2361, did some testing and ended up figuring out that the entire control circuit was good. (the relay was working and the signal was coming to trip it) turns out the red power wire was dead. So started cutting zip ties and following it, found a inline 25A fuse which reminded me that the fan was added post factory as a dealer update through mother deere. fuse was good so kept following the wire until i found my problem right by the hydraulic tank. Couple years ago I had to do a infield (well actually berried in a fill pile 40acers out in the woods with the boom all the way down) starter change on this machine. and said out loud while working on it man there are a lot of small wires on the positive starter terminal sure hope I don't miss one when I put this back together. (foreshadowing) well low and behold there i found the positive feed for the helper fan sitting on top of the hydro tank not attached to the stater. so much for my wrenching skills lol. Didn't really want to share my findings but hopefully some of you can have a good laugh at my expense. cheers guys and thanks again for the help.
