Headlamp Pods

[pwd95]

For anyone who is not on Faceplant..

Any headlamp gurus on here...
Headlights are on but the pods won't raise.
Any linkys to which fuse or relay controlls them...
Managed to wind them up manually but they went down when I turned the lights off.....
Cheers Guys. I'm keeping you busy!

Great website here with all the information needed http://www.wedgeneering.co.uk/TVR%20390SE%20p6.htm

Here's a couple of links that I found that are useful.

http://www.team.net/TR8/tr8cca/wedgelab/other/head...

This is in german, but google translates it OK

I also have a stripdown PDF that I found somewhere, drop me a mail and I will forward it, as I can't attach a file only an image.

Going up a level, there's a lot of useful stuff about everything!

THanks for the pointer.

Yes it made interesting reading when I found it a while back.
The bit I found strange is the 3 sections that are locked down to members are readily available on the interweb, whereas the other sections that are not locked out are much more useful.

In fact, I missed this one.

More to the point Wyn - when are you going to add the blower? And welcome back!

Hi Adam, blower would be an option I would never rule out. That ride in yours back in 06 ish at the Wedge fest is still vivid in my memory
This one goes like a stabbed rat TBH. It has the Tornado ECU etc. I'm getting a big stutter every time I accelerate though. Rather annoying. Will be opening a separate thread on that. How's the SX?

Hello, hope that you're sorted by now

If your pods are still suffering from erectile dysfunction, the following may help

Taken from http://www.wedgeneering.co.uk/TVR%20390SE%20p6.htm

Diagram 2

2. Lights are on (Low Beam). A 12v feed appears at one of the two diodes feeding the coil of the Headlamp Motor Control relay. This causes the relay to change over and it applies 12v to each pod motor via the Whi/Purple wires. Passing through one of the motor internal diodes and the closed switch contact, it is fed back to the coil of the Motor relay. The Motor relay changes over and applies 12v to the motor itself, which then starts to lift the pod. Note that the motor's internal switch stays closed during the lift cycle.



Think back a little

Did both pods fail to rise at the same time?

or

Did one pod fail to rise and then the other fail to rise at a later date..............................This matters much

If one pod failed to rise..........................................................Post here to verify

If both pods fail to rise with lights switched on and checked with column switch at dip and main position, (taking note that bulbs are illuminating)....................

Looking at the above diagram....................

See that one of or other of the 2 diodes (bottom left) supply a positive to the headlamp motor control relay coil depending upon what position the column switch is in (that being dip or main)

Going by the fact that the pods lower ok tells us/you/me/whoever that the side/head switch and column switch are functioning correctly

There is a problem with the headlamp motor control relay

or

There is a problem with the wiring to the headlamp motor control relay

or

There is a problem with the wiring from the headlamp motor control relay to both pods

Ask me how do I know?

It's like that it's just the way it is

I had exactly that issue recently, on another members advice I took the motors off, took the switch box apart, gave all the contacts a good cleanup by scraping them and contact cleaner, especially on the strip bit and they have worked fine since.

Great info guys.
I have been chasing my bad running problem. Managed to borrow a ECU Mate today so will report back at the weekend.
