my right hand headlight started playing up a few weeks back, and finally died. Heres the problem:

-All globes are new and test ok.

-i tried this:take the globe out,turn headlight switch on, plug a multi-meter into the terminals, it reads 12v. I plug the globe back in, it reads 0, then take globe out again, volts rise back up to 12v. WTF>?

any ideas?

I'm no auto sparky but maybe its the earth. Check to see if the earth wire for the headlight is grounded properly. I'm not sure where the wire would be though.

I had this problem on a van, the right side front indicator wasn't working and the bulb was brand new. When we took the bulb out and put multimeters on the terminals it would read 12v, but as soon as we put the bulb back in it didn't work, it turned out that the earth wire wasn't grounded proplerly.

Your problem could be similar, but thats just my guess.

plug the globes in, then put them back in the headlight fixture. This should earth it. If you try and turn the lights on with the globe dangling out it wont work, but if you plug it in it will. If this still aint working check the light switch out. it might be screwed?

ahhh found the problem, it was the wiring behind the switch in the plug playing up! cheers folks

The wiring behind the switch in the plug?

Can you describe it more exactly, please?

Because I have the same problem as you had, but found no solution to it yet...

    • Sorry no - The sandtrap adventure ended the day, happened at the end of the last session. At that time I wasn't hearing any weird noises nor were the brakes shuddering anymore. It was only when watching the videos that I remembered I had these sounds early on!
    • Did the noise appear after your sand trap adventure? Could be something got dislodged and is playing rub rub. Even a rock wedged somewhere.
    • Is there a shroud around the tailshaft spline into the back of the box? They can rub and make a horrible noise if they are not on straight/damaged. The heat might have caused it to grow too much in one direction and rub.
    • Strangely I noticed it either disappear later in the day, or not be present. I definitely noticed when I was crawling around that open wheel thingy entering the pits (that part was audible in car). Driving home and commuting around town for example, I didn't hear it. It's plausible that it was a brake disc or something still slightly in contact. The brakes absolutely felt BAD for the first couple of sessions, huge amounts of shudder and grinding as they got up to temp - And then I actually just forgot about it as the day went on/didn't notice it. The videos were from the morning when this was more present than the afternoon/drive home when it wasn't. I've asked around and got a variety of responses including handbrake shoe contacting hub, CV joints, CB tailshaft bearing as above, and clutch input bearing. I didn't test if it disappeared when clutch was in. I haven't noticed it in any of the other videos nor did I notice it when driving to that extent. More or less hoping the microphone at the rear license plate giving some kind of clue of 'something' but it looks like "spin stuff and see if you can notice it" is the way forward here. I could be smart and use the gopro mic and re-mount it to that location to see if the sound is still present at low speed actually. Sounds like a decent test whenver I have the CBF'ness to drive the car again. Given it's almost 40C for the day of the track day and the next 3 days after, the CBF is high. All I've done since getting home is unpack the car, remove the remnants of the lip and undertray and left it there. I was surprised how well the PMU Club Racers actually worked. The brake performance on the track was absolutely fantastic, best I've ever personally used, no fade whatsoever and the bitiness was almost too good, I was scrubbing more speed off than I needed to, but I also ended up infield when I started trying to scrape off ... less speed.... so...
    • Not really, no. Anything you would do is easily reversible.
