'66 Toronado vacuum system

8valve · 09-15-2006, 12:06 PM

Hi all,
I am having problems with the vacuum activated headlights on my '66 Toronado. First of all, the vacuum-cannister only has one line going to it, is this normal? The lights come up slowly when the switch is moved to the first detent (acc.the manual they should stay down) and when I pull the headlight switch all the way out then the left-side headlight goes down again when I accelerate....
I am in desperate need of a diagram of the vacuum-system, or good pictures of a good working system. I'm afraid that mine has been modified by the previous owner(s). Also, I am sure the system needs check valves, and I can't find any on my car. All help is appreciated. Thanks, Mick mick@w-andriesse.demon.nl

just a brief follow-up. The lights DO stay down with the headlight switch in the first detent/position (like they are supposed to) and the parklights do come on. However, the tank (with only ONE line going to it) does not hold vacuum i.e. when the engine does not run the lights don't move at all. Where is the checkvalve supposed to be that holds the negative pressure in the tank?
Thanks.
Again, please can someone send detailed pics of the setup like it's supposed to be to my e-mail address? (see above)
