Dash Light problem - 1989 Polo Classic - richrob

I have a nigling problem with my dash board warning lights. About 1 in 20 times when I turn on the ignition that lights fail to work along with the fuel gauge. The Hi-beam indicator works fine sugesting the the issue is with the the 12v feed from the ignition switch. Each time I remove the dash everything, of course, works fine.
Any suggestions????

Just to start. possible voltage control unit on alternator is playing up. would get it checked out. if found faulty replace alternator. if not faulty connection on dash may be problem. just a thought?

Solved it. The problem was in the flexi connector on the rear of the instrument panel. I'd already logiced that the problem was with the 12v feed, having buzzed out the supply and satisfied myself that this was fine, I then buzzed out the 12v track form the connector to the first component (a transistor), sure enough the circuit was open. Some very fine soldering of a fly lead from the connector to the transistor solved the problem.
