Tachometer stops at 2000rpm

Well, what did I do wrong?

 I had the dash out of my car to clean up the instrument's chrome rings and re-finish the vinyl.

As such, I had to disconnect all the wiring.  Upon reinstalling everything, it all works except for the tach.  At idle it reads fine but stops advancing at 2000rpm.  Did I mix up 2 wires or did disturbing the sender from its 50 year perch mess things up?

Thanks,

Ken

Did you disconnect the battery before removing the wiring?  Of all things electrical under the dash, the tach sender is one of the most sensitive.

 

Absolutely, there are way too many ways to create a short circuit back in that space.
