My UMA electric tach (~14 years old) has started to intermittently jerk around a given rpm. It will also revert to rock solid as before. Has anyone else seen this.
I removed the sender from the engine and there appears to be no mechanical wear. Also the only electrical connections are the multi-pin connectors and cable from the sender to the gauge and they seem solid. (I have had an electrical gauge - ammeter - problem before that turned out to be a loose screw on a ring connector.)
