Fuel gauge illumination

[richard bradbury]

I have a1992 Vauxhall engined HPC. How easy or difficult is it to check and replace the lamp bulb in the gauge?

Not too hard:

1. Remove the gauge to see how it all works. 
2. Remove the lamp.
3. Find a matching replacement lamp. (You can now get LED lamps that fit, but you might then want to change them all to match.
4. ...etc.

PS: It's not essential to have either a wiring diagram or a multimeter, but it wouldn't hurt. ;-)

Thanks for that. My problem is fixed vertebra in my neck which makes poking around behind the dashboard a literal pain. That and being 71 doesn't help!

Sorry to hear that. In that case I'd definitely remove the gauge first.

I would use a smartphone to photograph under the dash and to make sense of everything. The gauge is clamped to the dash using a U shaped bracket and two ribbed finger nuts. If you undo the nuts, you can then pull the gauge out of the dash.

There should be a white connector which you can then pull off. The remaining pair of wires go to the bulb holder, which is a bayonnet fitting in the back of the gauge. Twist and pull to get it out.

Refitting is reversal of removal.
