As above, The first suggestion is always the same one :- Loose earth connection.
Those thumb nuts on the back of the tacho case can come loose easily.
Next:- Has the tacho got a reliable 12 volt supply when driving. Fix up something like two wires from the back of the case to a lamp lying on the passenger seat.
Best of luck
