Sticky tach 90SP36

[one_dusty_hoot]

Trash in the jeweled pivot bearings, or hair spring return,
warped or trash on face plate, intermitently open or shorted
coil winding, logic circuit, solder joint or contacts of the
dip switches, post connection loose.

Fortunately you have isolated it to the meter by tapping on
the glass. Check mfgr for repair shop however repair may not
be able to duplicate problem and not fix.

Tape the connecting wires while you have it out so you can
still use the coach.
