Sticky tach 90SP36

[Chuck Wheeler]

Chuck,
I had the same problem. Unless your Tach is different than mine (Teleflex)
it is not designed for repair. With nothing to lose I carefully removed the
front bezel holding the glass by bending the edge where it had been crimped,
removed the nuts on the connectors and took the works our. There was a wire
and connector used to set the correct frequency for the pulse generator and
the solder was broken. Since I wasn't going to change the adjustment I
removed the wire and connector and bridged the correct contacts. It has
worked fine ever since. I already had the dash out, fixing the tach took
about four hours. You can get a replacement at a marine that handles
equipment for diesel yachts.

My tach will frequently jump from around 2000 to 1000 (with no
significant change in real rpm). And will continue to move up and down
following rpm changes until I tap on the class. What causes this and
what are the remedies?

Thanks
