I don't know how to reply to a specific message in
a digest, all messages have the same (imperial club) address on them. Oh
well, this is for Dick Benjamin who was good enough to reply to my question
about vacuum valve testing. There are four "vacuum check valves" in the
1968-etc. Auto Temp system. It would be nice if they were simple in
and out valves as you describe. Actually, there is one valve with three
hoses connected to it, and three valves with four hoses. The hose
connections are arranged with two on one side and two on the other, except for
the "odd fellow", one of his is missing. I have not had experience with check
valves with more than two ports. Each valve has an arrow on it which
points perpendicular to the hose connections. Perhaps I need to
remove each valve from the system and experiment until I can determine
that one of the ports is where the vacuum source connects, and the others should
trap vacuum if the source is removed? Please advise.
Thanks, Dennis
