I have a 450 with overheat light coming on. Here is what is going on.
Light comes on - fan doesn't run..
Pulled plug on radiator - jumper wire on plug and fan runs.
Replaced thermo switch on radiator - fan doesn't come on.
Removed the pack in the battery box and replaced with a 20 amp inline fuse. Started engine - light came on - no fan.
Installed a manual switch with relay. tapped into the blue wire going to fan. started Rhino, it heated up and light came on. Flipped switch, fan came on, cooled down and light went out.
Help !!!!!!!! I don't understand why the fan won't come on by itself.
