headlight vacuum switch
Posted: Sat Jul 22, 2017 6:00 pm
Hello Folks
another job underway alongside sorting dashboard is the vacuum circuit. My car came off the road in th mid seventies, with very low mileage / usage. I believe that most of the components are servicable, however, before installation I like t check them out.
The vacuum headlight switch looks fine and mechaniclly feels reasonably smooth, but i want to test functionality.
Can anyone tell me which feed is which, and how the valve should behave when functioned? Is it just open or closed, or does it vent as well?
thanks
Bob
