Got a 91 Scala. MOT fine except full beam tell tale not working.

Had the binnacle out, took bulb out, tested and bulb fine!

Any ideas where to go next? I'm stumped...

Not electrically literate so any ideas in layman's terms please :-D

For a test pass, stick a blue 12v led into a small project box, run a feed to it direct from one of the high beam headlights and blue tack it to the dash. You can then take trace the fault in your own time

yeh think thats the answer for now, right on Nate.

Worked out the white with blue wire on white loom is for high beam indicator and brown wire on white loom is earth.

So does putting a multimeter between them test if power is getting to the PCB???

Can test this in the morning, fuse no.9 is fine.

Does anyone have a diagram for the relevant indicator stalk?

Fixed! Dodgy contact on stalk mechanism, disassembled, cleaned. Works great. Need new bulb as bent it and had to use battery bulb to test.

Off to Maplins to see if they can help.

You need to copy and paste the link and remove the help at the start of it or it doesn't work.
Perhaps JackPong can edit the post to rectify the issue....?
