I think that the most common failure is the magical
thermister, which acts as a temperature compensator.
Its failure is typical of functioning tachs, that are
out of calibration.

There's an adjustment pot on the back of the tach. I am no
electrician, but there are also transistors and condensors inside that
can go bad.
