Challenger 750 UTV

[Davisgravel]

I have a 2018 750 challenger utv, the cooling fan started running all of the time, even with ignition switch off, it will run till it kills the battery. I've checked the sensor on bottom of radiator, it's an open circuit no continuity, I found 2 more sensors on top of engine at coolant hose, was able to check 1 of those and it's an open switch as well. I can disconnect all 3 sensors and fan still runs. Only way to kill fan is to unplug it just back from fan motor in wiring harness. Any suggestions would be greatly appreciated.

Does it have a fan relay that might be stuck on....

It has a relay, I have it off right now, doesn't seem to be stuck on but I may not be testing it right
