Cause of Gauge Flicker
My pressure and temperature gauges flicker (don't know a better word to describe it). They operate normally at startup however they tend to jump around from a point that I believe to be normal. For example, if the revs of the engine dictate that I should be around 3 bar pressure, the needed will sit at three bar but jump up and down about 1/2 bar intermittently. I haven’t been able to determine why this is occurring. No other gauges have this happening, just the temperature and pressure.
Any thoughts as to why this could be happening? Michael

Loose ground wire in instrument area. Groups of brown wires bolted to chassis in 2 -3 spots.

loose ground or maybe a dirty or loose connection at the gauge or sender.
