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.
