Electrical problem

When I first start the jet, the gas gauge and temperature gauge read correctly, but as I drive, the gauges go up, then down and up and down continuously. Any ideas on what is going on?
Thanks,
John

  • IRV is not working after it heats or the ground is loose at the gauges.
  • The 5 volt regulator is not stable.   Mounted on the  instrument cluster body.   
  • I always blame stuff like that on Gremlins....
