Headlights with Viagra

[Gizze]

Hi,
I'm in the process of getting my car back on the road. Having put 'new' pods on the vacuum system and got the engine to run, I now find the headlights come up (eventually), but then I can't get the things to come down - even when the engine is turned off, they still stay up. It's a 1970 car with the non fail safe system (as far as I can tell). Only by breaking the vacuum (disconnecting the hose) do they come down - Have they been dosed with Viagra??!!
Any help would be very much appreciated.

With the engine off, how easily do they move by hand? Easy, with a pronounced snap downwards or can you feel friction resistance, rather than the hiss of air being compressed/moved in the pods? How is the vacuum switched - electronic valve or pneumatic? Could be a sticky/blocked control valve.

Gizze,

Whatever your name is (Gizze?), and where you're from, it sounds like a faulty vacuum switch or non-return valve.

I think the vacuum switch on the dash might be plumbed in the wrong way and you need to reverse the two pipes. One of them, when the switch is in the "down" position, vents to the atmosphere to allow the pods to go down.

Hi

A few pics of the non-failsafe dash switch on my 1968 +2. It is a really simple switch; when you pull the knob the rubber block uncovers a pipe.

Swapped the hose connections on the switch - headlights now go up and down in an orderly fashion. SUCCESS.
Many many thanks.
