Tacho problm

Hi,
my tacho has stopped working, on the faceplate one of two screws has fallen inside the casing. I have opened it, and found the screw and what looks like a copper washer. I don't see any logical place for that washer, and when I put the tacho cable inside the cable slot and spin it, the needle is not moving. Since I don't know where that washer goes nor what it does, I don't know if my tacho is dead or fixable.
On the photo you can see this washer under the hole for the little screw that fell off.
Any help, any guesses?
