    You have what appears to be a systematic failure of your wiring system supporting those gauges. There is either a BIG short or source of spiking voltage from either a Dying alternator or something else that spread the electric storm under your dash affecting everything until they burn out. Or burn if you have a hot enough short to ignite something.

    That truck is not to be driven at all until a shop has had a chance to trace each one of those gauges and it's associated wiring, sensors and so on all the way back.
     
    6wheeler Thanks this.

    On the older Pete's there was a big breaker behind the dash on the far left side that powered everything in the cab, including electric gauges. Worth a look to see if yours has it and clean up the connections.

    Sweeping gauges mean it is not recieving data.
    Head to the link below and click on the 387 technical manual. There is a section to diagnose sweeping guages.

    I agree. Just like a twitching body with a headshot. No data no real meaningful activity.
