Hello David,
For no obvious reason my analogue tacho did exactly the same thing and
I tried the "standard" fix of reversing the polarity of the wires from
the pickup and the problem went away. I had even changed the tacho and
it made no difference. Black magic rules.
Cheers,
Mark

at rpms above about 4500 (giving the appearance of 'kicking' or jumping
up and down by 100 or so rpm) and not giving steady readings (when the engine
is running steady as a rock). Has anyone else experienced this and what did
you do to fix it? I have tried to find loose connections but there don't appear
to be any.

system?
