Headlight Pod Issue
Discussion
Left sided pod comes back up some when I shut the lights off
Is this fixable by adjusting the linkage arm or is it internal/electrical
This is a new/replaced motor
If I manually put the left one all the way down (turn it up --> down flush) it creeps up as soon as the battery is reconnected
Thanks!

From what you describe, this could actually be an electrical problem ! (yes - really)
What a lot of people don't realise is that a wiper type motor doesn't just stop dead when power is removed, unless you SHORT it.
( i.e. connect the power wires together). This will make the motor freeze pretty much instantly.
So the relay which powers the pod motor is actually a 5 pin one (= a two way switch) and it connects the 'live' wire on the motor
to either the +12 volts when on or to 0 volts (=earth and other wire) when off.
So if the wiring has been fiddled with, this might be the cause. It will only lift slightly with this problem, and it's more likely the adjuster or
motor not fitted quite right, but just adding this in case ...
[ This is also why the windscreen wiper switch is more complex than you would think, as the self park setup ALSO shorts the motor so it stops
right at the bottom of the screen ]
Hope that's useful -

This is very good information, I totaly overlooked the electric breaking of the motorWhat a lot of people don't realise is that a wiper type motor doesn't just stop dead when power is removed, unless you SHORT it.

Should the electric breaking not be working I would expect the motor to also ride past the fully elevated position
Below is a link to the diagrams, I notice these digarams don't show an earth at the relays for motor braking

No, and it should.......those two unconnected poles go to earth on mine....(well, equivalent that is, as it's an older 2.8)http://www.wedgeneering.co.uk/TVR%20390SE%20p6.htm
Yes, agree. If the problem only happens at the bottom then it's probably not this, and a mechanical/alignment problem.
But I have sympathy for owners who tear their hair out for an issue which is so damn simple -
but AFTER someone points it out and everyone screams "Oh SH*T!!! I should have though of that "
Been there too many times.....
