If anyone has any idea, that would be great....
So, put a new dash in this morning, and i don't know whether I've knocked something or what but now when I switch on sidelights or main beam, the following happens! (its a three-dial dash in front of the steering wheel if that helps).
1. Fuel gauge goes well past full, even though its actually only half full.
2. The indicator lights in the dash both light up - though the actual car lights on the car don't.
3. Full beam dash light doesn't light up when used, again the actual full beam does work.
4. Rev counter needle slightly goes up!
So it's like the centre gauge of the three has got issues, even though before it was absolutely fine.
