Had my first niggle when the fuse went on my main beam during the journey back from Manchester, put a smile on face mind you, as its a reasurring TVR niggle

Came to check the fuses today after looking through the manual and I have an L-shaped arrangement of fuses rather than them all being inline as in the manual.

The fuse (20 or 21 - forgotten now) was 10A rather than 20A rated, so I wasn't sure whether it was the one for the main beams or if a 10A had bene put in there by accident, and hence the failure.

Didn't get around to checking whether that fuse had blown or not which was a little silly I guess.

Does anyone have a fuse and relay diagram for the newer layout at all?

Cheers :thumbsup:

Has replacing the fuse fixed it?

It's usually the connections to the light control box that burn out instead.

Not had the chance as yet, will try when I'm next out there in the light...

Where's the light control box situated and more importantly (if it has gone) what is the cost?

The light box is in the boot on top of the fuel tank, mine was on the right hand side, but that doesn't mean yours will be
Check the connectors and if any of them are brown and burnt then get the soldering iron out and replace them. I just cut the wire, drilled a hole in the box and soldered a bypass wire (with spade connectors so it could be removed) to the connector on the circuit board.

Think I might leave it until my soon to be booked service then...

I just hope you have more luck than I did when my car suffered the same fate!

Like yours, mine is fitted with the gas discharge lights and according to the dealer that I had just bought it from, the control boxes are made to order by TVR. Not only that but there seems to have been various designs of control boxes fitted for these lights!

Good luck and I hope it isn't a control box fault - I had to wait almost 6 weeks........

Lucky I live in London and we seldom need full beam then I guess!

Booked in with Andy at APM next Tuesday and he's mentioned three key potential areas for the problem: fuse, relay and control box. I'll cross my fingers for the first two...
