I have a 915 combine and I'am having problem with three shaft speed sensors working they are the fan, chopper, and rack they have magnets on them the wiring is fine and I've adjusted the fan nothing could the sensor it self be bad?

Yes have seen sensors go bad over the years. There are no magnets just a ferro core that interupts the electric field of the sensor as it goes by. Find some used ones or move one from a working positon and see if that cures the problem.

if the sensors are bad should they be making a clicking noise when a magnet is runned past the sensor it self?

Never heard them make a clicking sound, trade a working one from shoe and see if problem moves. If so you need sensors. If not then a wiring issue exists.
