Looks like the weight or magnet came off, from the clean square where it was attached. Go get a dime sized disc magnet and glue it on where the square is. Make sure it clears the pickup by 30 thousandths or so and give it a try. Youll only be out 30 cents or so. Cheap fix possible.

Today I finally got around to replacing the sender with the part that Richard5933 recommended.  It's a universal part so I had to bend the bracket 90 degrees and drill a 1/4" hole for the mounting bolt; I wired it up and decided to try that first step before going thru the task of removing/replacing the old magnets on the pulley.  IT WORKED!  Didn't have to replace the magnets and the whole procedure start to cleanup was about 35 minutes! 

I'm a bit baffled why the shop couldn't figure that out when you guys did with just a photo and a description but, whatever...

Richard5933 gets the prize!!!  I'm very happy to have a functioning tach for my upcoming 6K mile trek through the Heartland of America.

Glad to hear it worked out and was so easy.

Why couldn't the shop? Simple. They didn't want to.
