I'm not sure what you mean by "manually compressing the vacuum motor" could
you please clarify.
If I ground the line to the vac pump and make it run - will it cause the
diphragm to compress?
I did the tests on the vacuum motor per Bentley and it did pass - ie it ran
when grounded and the vent valve clicked when grounded. I do have another
vac pump that I installed a while back (and took back out) that did not make
the CC operable. I can test it too.
Thanks for the help

Yes and Yes ...
... the proper test is to pull the vacuum line from the CC pump and
apply suction there ... and you can do this by manually compressing the
vacuum motor or by using an external vacuum pump ...
... if anything the dual filament bulb holders help ... you've got two
more high current filaments in parallel to ground ... and the aux ground
strap would help mediate any resistance in the ground path proper ...
I don't remember from your original post ... have you tried a known good
San Jose, CA (USA)
