My little man bought a 2011-12. 300 grizzly the fan has been hotwired, it works by twisting 2 wires together and it comes on when it gets hot but kills the batt if left on. What part does he need to replace?
That's right u can connect when cold but fan only comes on when hot. But with out the bypass it doesn't come on at allSo when the ATV is cold you can connect the wires and it will not come on until it's hot? Does it shut off after running for a few minutes or just run continuously after that? Rough guessing a relay and maybe the temp switch.
