Mystery of high beam and driving lamps not working?
Discussion
I've just noticed following my Griff being retrimmed that the high beam and driving lamps are not working. The blue indicator lights up on the dash but the lights don't actually seem to illuminate and this happens whether you pull the left stalk towards you or away from you.
I'm presuming all 4 bulbs haven't suddenly failed at once so would welcome any pointers! Could it just be a fuse? It's an early pre-cat Griff so am grateful for any advice!
It's hugely annoying TVR don't label their fuses with a function! I do have the Steve Heath bible but am finding it difficult to identify which fuse if any could be causing the problem!
Many thanks in advance for those more knowledgeable than me!

If the high beam light comes on then all the switching and fuses for that are working.
Which leaves fuse 20 (Second to last on the right) or relay 11.
Either of these could well have been disturbed during a re-trim as it gets pretty cramped trying to glue carpet down in the footwells. (particularly if you are 16 stone and 71YO).

There seems to be some confusion in the Owner Manual and the Bible as to naming the front lamps
All I can offer is how the lamps work on my Griff in the photo they are not standard but the lower lamps are main beam. (underneath the ThumbSnap note). When flashed or on full they all light up.


Hopefully other peeps can help with the circuits.

There will be a fault on the driving lights, the other lights should remain on dip, this is going by the information contained in the above page

According to my fusebox layout (1992 4.3) the Main Beam fuse is second in from the right and should be 25A
there is also a Main Beam relay which is bottom right
Here is a tip for you. Find your fusebox in the Grrifith Bible, copy and print it and put it under the mat in the passenger side. Its massively useful to have done all the work up front to identify your fusebox and have them documented in case of breakdown.
