TVR Chimaera wiring diagram
Discussion
Hi Steve,
Yes you sent me the wiring diagrams, many thanks!
I found the problem on my car within 10 minutes of studying your diagrams, someone had swapped the fuel pump relay for the wrong type, (changeover relay instead of 2 x normally open contacts) causing the 02 sensors to drain the battery with the ignition off, and not to be heated with the ignition on.....so 2 problems solved at the same time....

I've seen that too many times. Even had a customer who transported his car to our garage with the same issue. If I turn the key and don't hear the pump run then the pump relay is the first place to start. It's pretty much the middle of that circuit so you can test down the line to the pump or back up the line to the ECU.Glad the diagrams helped. I created them when we first started working on TVRs as all the other circuit diagrams available do not show what happens within the fuse/relay box and for the most part the dash also.
Although I'm now retired I still amend them as I find new variations so if anyone finds differences or mistakes send them to me my email is in the bottom left corner of the first page.
