This light on dash has started to come on when put lights on, it goes brighter as you rev it! rather than dimmer as you rev it... the new alternator is working fine the volt reading at battery was 13.8 anyone know what this is?? Thanks

Bad earth at back of dash maybe , check the volts at batry with the engine off then on and make sure it goes up when running

Cheers! yep volts go up checked already, will wiggle some dash wires n c what happens, Ta

earths are always shit on the back of them dash's . if you know what your doing it would be worth replacing them but do it one buy one . dont just rip every thing out
