Dash lights!

[greg.cranwell]

After much thought I started working on my car again after ignoring it for the last few months.

None of my dash lights up currently, none of the switches, the instrument clusters or the gauges. Doesn't bother me during the day however at night it's a bit rubbish! Fuses are all fine and I've had a few bulbs out which appear fine.

Any suggestions or wiring diagrams available if I was to try and replace some wiring and get this sorted? It's not the biggest problem I have but its one I have been putting off since I bought the car.

Cheers for any help!
