Dashboard Gauge issue

Hi
We have a 2009 Tiffin 36QSH which has developed a strange intermittent habit.
On start up often the dashboard dials remain inoperative but the coach starts fine, but the Air alarm continues to sound. If I turn the headlights on the gauges & rev counter all liven up & the alarm silences.
The question is - has anyone else experienced this?
I have checked the connections on the dash & the fuses all look fine.
It seems there is a bad connection somewhere but when the 12v powers up the dial illuminations it resolves the issue.
I have also experienced the alarm coming on & the dials dropping to zero/off whilst driving but the engine & transmission all working fine. If I switch the headlights on, all is fine again.
Not a huge issue as I am now starting journeys with the lights on & driving without any problems.

If I could resolve it would be great.

Regards

Arthur

Have you pulled the dash and double checked all the connections on the daisy chain for the guages?

Sounds like an electrical ground issue. Take a video of the problem so if you can't fix it, the service tech has something positive to start with. Good luck
