Oh...Maybe I'm mistaken but arn't you supposed to use the starting current
AND the continuous current to figure out the correct fuse size? If these fans
run without blowing out a 50 amp fuse, wouldn't that be the logical size to
use? hmmm...food for thought :)
Does anybody know the size fuse used in a Viper for the fan?
Thanks,
James
