Just a guess, signal relay could be sending little voltage spikes through the instrument cluster circuits. Could be bad relay or a grounding issue.

Any time my speedometer twitched it was low voltage, and I have had mine for over 21 years.

That would alway happen when my voltage regulator was ready to go out, then when driving with it for awhile Id see my clock dim and the fun was over.
I though keep replacing voltage regulators till I fixed and put in new wiring by the junction block, my alternator wire fryed to were even when I used my brakes you'd see everything dim.

My '87 has done the exact same thing for over 10 years now (on mutilple Alt.). I think it is just the inherently bad wiring these cars have.
