Hi Chaps
My headlights!!
They won't go up when the lights are switched on, but if I wind them manually by hand they go up and stay up. When I switch the lights off they go down by themselves.
If i only manually wind them up a little way, like an inch or so, then switch the lights off, they go all the way up and then all the way down in one go.
If I disconnect the battery, wind them up manually (again only has to be a few turns), then reconnect the battery, do nothing with the switch, they also wind all the way up and all the way down by themselves, .
I've checked the relays with a multimeter, the motor control relay is switching, but the two motor relays don't seem to be doing anything (they do have power feed's but are not switching). I have tried swapping the relays for brand new ones, makes no difference.
In short it seems that they are not getting the instruction/signal to go up, however the motors are working, have power etc as they are getting the signal to go down and they work in that scenario.
Exactly the same on both pods - all the lights work, main beam, flash etc - just no raising of pods when switched on.
Is this diode(s) that need replacing possibly? I've read the wedgengineering pages but I'm not 100% sure exactly what I should be replacing.
Any tips appreciated
Cheers

I had the same issue recently (only on one side though)
On mine it was corrosion on the contacts In the little housing in the back of the lift motor not allowing current to flow
Get the pods in the raised position
Remove the fuses to the lift motors to stop accidental movement
Remove headlamp and headlamp pod
On the back of the motor remove the little cover plate (4 screws with 6mm heads)
Clean contacts - they look very delicate so I just sprayed with electric contact cleaner rather than physically cleaning
Replace cover
Replace fuses
Check for correct operation
If all’s well leave in raised position
Remove fuses
Reassemble
Replace fuses
It’s a good idea to clean the electrical connections for the lift motor and headlamp while your there and have easy access
Good luck

I use 10mm piece of 1200 wet and dry folded over, then drawn under the contacts. It is always good to check the two diodes continuity whilst you are there. A@

Basically the motors work on a 'points' electronic system with all the reliability that comes with it.
In typical TVR fashion the whole set up is heath robinson and poorly carried out. It doesn't fix it self over the years.
Pods out. Motors out. Check electric signals /wiring. Clean up 'points' on side of motors. Make sure the motors are in down setting. Then set up the pod heights and actuator arms.
Sounds complicated but it is pretty simple when in front of you. Only do one side at a time and accept that parts are worn and / or broken.
While using the other side for reference don't assume it is correct. It is unlikely the factory set it up well to begin with and likely to have been messed about with by others.
All that said, I think it was TVR Barn who were looking at using linear actuators to operate the pods rather than the butchered TR7 set up TVR used.

Thanks for the replies gents - the above sorted it, a lot of crap around the contacts, did a little careful scraping with nail scissors and spraying contact cleaner, after that tested with a MM and all seemed good - refitted and they are working On mine it was corrosion on the contacts In the little housing in the back of the lift motor not allowing current to flow

I gave up with the prince of Darkness stuff and fitted a pair of motors from a Toyota Celica, it did require a bit of rewiring in the fuse board due the the way the Toyota motor limit switches worked but 8 year on and not a wink in sight !!
This is clever and I like cleverI had to modify the mounting bracket, drill some new fixing holes and modify the lift motor relay wiring, from memory due to the TVR switching the ground and the Toyota switching the 12v side of the relays I swapped the 12v & 0v around. This also made the fog light switch to send the pods into and up / down frenzy (discovered durin the MOT) which required another change in the fuseboard...
The Arms are then swapped from the Lucas motor onto the Toyota one
Since I did the mod in 2013 I have never had to lie on the ground to manually lift the headlamp pods - although that function does still exist.
