thanks for that tut very handy indeed, although the alfa gauges are a sealed unit inside the casing, you can take the tacho/rev's out the outer casing which leaves you with the face needle and the rear circuit board, this is also in a casing, basically the inner casing sits inside the outer casing, the clocks only have 3LEDS each which power the backlight as far as i can tell , the leds for the warning lights 'seem' to be inside the unit, however opening the unit up to see if there SMD's or LED's is a task in its self lol
as i cannot see an easy way in without damageing the board/face or the needle
i may do ti one day but currently dont want to F*** the clocks up by trying as i cannot really afford a replacment at teh moment
