Chimaera Brake Lights Problem

[BryanWilton]

Help!

Brake lights don't work

Fuse is fine, there is 12-Volts at the switch & the switch is operating correctly (Bulbs are ok)
The Earth at the lights is fine, but no live getting to the lights

Does anyone know if the Brake lights are operated via a relay & if so which one?

The TVR Bible doesn't tell you if any of the relays operate the Brake lights, but does tell you if they aren't working to check the fuse, switch & relays

Obviously would greatly help if I knew which relay to check or if they are even switched via a relay (not convinced they are)

I also carried out some rust proofing on the chassis recently & wondered if theres anything on spade connectors that I may have knocked off which goes to the brake lights (managed to knock the oil pressure wire off)?

Any ideas?

They are fed by an ignition feed so worth checking that other ignition related functions are also working, including the ignition relays. Yes there is no specific brake relay. I think the next stage would be worth checking the feed wire back to the switch. IIRC there are some connectors in the door lock cubby hole behind the seats. I suspect it might be a corroded connector.

When this happened to me there was a bad connection at the connections in the carpet covered panel behind the passenger door lock.

Spot on guys!

Pulled apart all the connectors behind the passenger door
There was no sign of corrosion but there was signs of vaseline being smeared on connectors, so I guess theres been an issue here before

Sprayed inside connections with contact cleaner, reconnected & all is well

Thanks for your help...

No brake lights - so will check these connectors tomorrow.

I've just had a similar problem but it turned out to be the brake light switch that was faulty. Ordered a new one from TVRPower and fitted it last night.

Is that the sitch that sits on the brake pedal ?
Was it easy to fit ?

Piece of p*ss,if you want to verify thats your problem then switch on the ignition and short out both terminals if the lamps light up theirs your problem,switch either needs adjusting or is knackered.

I had the same problem - must be the season for it. Dropped into Fernhurst (not having the part and not wanting to break a nail) and they sorted it in seconds. Really easy fix - the mechanic commented that it was one of the only TVR fixes that you didn't need a set of tools for!

I had exactly the same problem - did all the usual checks (switch, fuse, bulbs). No joy. Did a search on PH, came up with this suggestions and ... hey presto! It worked.

Just wanted to say again how great this forum us - hardly ever fails to provide you with a solution. Big thanks to all those who contribute!
