Is this vehicle used for snowplowing or does it have any aftermarket accessories that use a lot of current?

Have you checked the cable from the alternator to ensure it isn't shorting out somewhere? Thats a tight engine bay in there and things do rub.

Wonder if you could get your hands on an amp clamp and see how much current it is putting out.

That's interesting. Which fuse did you pull? Was it the 60 amp? If so, something in the ABS system is using a lot of current and overworking the alternator.
Has the ABS light been on before removing the fuse?
We'll keep this thread open, so let us know what they find out about the ABS system.
