Hi all
I have an illumination problem my oil pressure gauge is fine as is my temperature gauge,but my speedo bulbs don't work tried new bulbs but still no joy
Could it be the earth on the back of the speedo itself
Any ideas would be helpful
Thanks Mark

Check the PCB on the back of the dials as it can be prone to damage, if there's a break in one of the tracks it could cause the illumination to fail.

I think the OP means the big Speedo from '59 to the 80's.

If you have sidelights, the earth seems likely.

I have this binnacle so not new enough for tracks
Sorry for confusion
