3pete Posted April 26, 2016 Share Posted April 26, 2016 Have a 2005 CH600 and the gauges in the dash cluster will go off but instantly come back on. When they come back on the seat belt light will come on and the chime will sound. The engine never shuts down when this happens. I want to think it is a ground problem but am not sure where the dash ground is or where to start the troubleshooting process. Anyone have any ideas?

fjh Posted April 26, 2016 Share Posted April 26, 2016 These dash panels weren't the greatest the dash panel printed circuits break over time!

DCR Posted April 26, 2016 Share Posted April 26, 2016 Several years ago Mack had a service bulletin about this issue. It told how to run another ground wire to correct this situation. If this did not work then the gauge cluster needed replaced. 2 Quote Denny330-550-6020A "Mack Pack" Charter Member Link to comment https://www.bigmacktrucks.com/topic/44986-dash-guages-go-on-and-off-intermitantly-2005-ch600/#findComment-331618 Share on other sites More sharing options...
tjc transport Posted April 26, 2016 Share Posted April 26, 2016 on mine it was the wire going into the plug that plugged into the panel. i unpinned it and re-soldered the ground wire into the pin, then put the pin back into the plug. solved the problem, and that was almost 2 years ago.

JerryB Posted April 30, 2016 Share Posted April 30, 2016 5 or 6 years ago the wiring harness had corroded at the panel plug in. Snapped it apart squirted with PB Blaster. plugged it back in and no more trouble.
