There won't be any fuses on the 2001. (There might be a main circuit breaker, but it handles everything and isn't specific to the AWD system.) There are several factors that enter into the AWD not working including the gear shifter switch, the reverse override switch and the front axle coils. Here's a link to a site that has service manuals on-line from Polaris. (They make you create an account first, but then it's free.) It might be worth a shot to see if you can get a .PDF of the manual for your machine and see it it's any help. Here's the link: Polaris ATV, Snowmobiles, RANGER, Victory : Parts Manuals
