Yes, a 2022 800XC.
(should show in the sig line now, just for you . . . )

Yes, when I get a moment I was going to check the connections and the sensor first and start there.
The bar actually CYCLES with the rest of the dash when you first turn the key on, just appears to be not getting the signal to the idiot gauge.
I can hear the fan cycling on and off and it appears to be "normal" per se.
It doesnt come on until the bike is actually warmed up and the . . pattern of its cycle sounds the same as lasts for the usual duration
