gauges on go out....

[bpwsross]

I have a 2004 Air Nautique SV 211 Team....when starting the instruments all work well - fuel, temp, pil pressure, speedometer, tach, etc....after a few minutes they stop working and some times even the hours guage goes out....perfect pass continues to work and gauge just fine. I am guessing there is a back ground connection somewhere...any advice about where to begin to look? Or other opinions?

Thanks

I would check the connections on the box in the storage compartment on the starboard side on the outside wall behind a black plastic cover, look for a 4 pin connector that has a purple, red,and black wires check for a loose connection or corrosion in the plug, also look for corrosion in other plugs, because the pressure sensors some times leak and get the electronic board wet and causes weird problems like this.
