Bukh Tachometer not working

DV 20 Bukh tach stopped working after two years on the hard.
No spiders, and purchased a used tach but same result.
The sender from the flywheel wiring is good and I get anywhere from 1.5 volts AC to 5.5 volts AC from idle to max rpm. on the voltmmeter.
Any thoughts on how to check out the tach etc appreciated.
Thanks
Brian
