I can certainly replace the switch. I pulled the servo out and hooked up a vacuum pump then actuated the valves to let the vacuum in. My question is does the diaphragm hold a vacuum? It appears to be pulling in outside air. If it relies on a lot flow from the reservoir to compress the spring then that might explain why the vacuum pump doesn't cut it.
No problem. Checking the servo was just a shot in the dark. I don't think any of the stores around here carry one so I may have to order to see if I'm right.
I got the part put in today. Doesn't seem to set at speeds under 50. Perhaps I didn't keep a steady speed or a speed sensor? However it works at highway speeds which is all I wanted.
