I mentioned this in another thread, But thought I'd concentrate on this only in this one.
I have the warning on the dash as soon as the brake pedal is pressed, Originally the third brake light only had about 3 bulbs working so I replaced all the faulty ones for new 1.2w bulbs, This hasnt cured the problem. I checked the other 2 and they are ok, I changed the N/S one just to make sure (couldnt get to the O/S) but still the same. I then got another bulb and wired it in parallel so the circuit drew more current but it still didnt get the light off the dash, Its doing my head in now.
I Have now noticed that switching the xenons on also causes the warning to appear.
I checked the voltage to the third brake light and it was 11.2v, battery voltage was 12.1v so theres some loss there.
Anybody have any ideas what it could be? bad earth maybe?
