Dipped beam wiring (and hello from newbie)

[saml666]

Hi, just got my first chimaera, an old L reg 400.

I have a very low mileage typhoon cammed 4.6 ready to swap in to liven it up and will shortly improve braking and suspension etc.

The dipped beam doesn't work, I've got the connection diagram from http://tvr3.dspen.com/fusebox/mo264.html and the fuseboard diagram from my manual and now have a question...

The manual says the main beam relay is bottom right (no.11) and dipped top left (no.1) however on mine they appear to be the other way around. I appreciate that consistency and TVR don't go together so it may not be an issue but since someone has been working on the wiring on my car previously I thought I oughta ask in case it could be the root of the problem.

BTW, main beam works with the stalk pushed toward the dash and both relays appear to operate when you switch so the problem must be on the power side...

Everything else works OK but the quality of the wiring work is a bit poor so I'll be tidying it and relocating the fusebox/ecu more securely

Thanks for any advice,
Sam

I assume you've checked the lamps?

Hey thanks for the reply, good point, I did. Actually that raises another question, I got to the bulbs through the sealed/screwed panel in the wheel arch but is access as good via the front grille?

My tests confirmed that the feed to the dipped beam is definitey dead and the bulbs (both filaments) are definitely alive.

I know if all else fails I can run a new feed as I have a working relay but would be nice to fix it within the original loom.

Oh yes, I also swapped the main and dipped relays around in case the contacts inside were dodgy but again, only main beam worked and dipped remained dead...

Cheers,
Sam
