Boat Gauges Bouncing

Hello everyone, hope all is well. Wanted to check in if anyone has experienced this issue before. When engaging the taps button on the throttle, the gauges start to bounce every click. Gauges Bouncing: Fuel, Volt, Temp, Oil I am confused at this point. Everything is tight on the gauge bolts and made sure that contacts haven’t rusted already.

Most likely a grounding issue. You will need to check the wires end to end.

Check all the ground wires, not just on the gauges.
