97 Omega Dash Lights go off after 20 minutes

[aaron]

Hey everyone.
Strange problem this, but after 20 minutes of driving all the dash lights including the gear selector lights go off. Even if you switch all the lights off and on again, they will come on for 1 sec then go off. Great fun if its pitch black....

Any ideas? :-/

1) Earth fault somewheres.....  Try firmly pushing the instrument binnacle back into the dash to ensure connections are seated as well as poss.

2) Dashboard light dimmer beside headlamp switch is fubar.  Try replacement as they are cheap enough from the scrappers....

moving to the electrical bit....
