Seems I have a loose wire somewhere, but where I am not sure.
In my 95 sea ray, when I am going past 20mph or when its really bumpy, the volt meter jumps from 0 to 15volts and the gas gauge goes from empty to where its currently at.
It must be a connection somewhere, but I checked all the wiring behind the gauges and its fine. Do you think it could be at the alternator somewhere, or on the ignition switch?
Anyone have something similar happen?
