Another vacuum generator question - Chuck Wheeler - 09-13-2006 11:10
Kerry,
I put a global cruise on my 82. The servo is electric. I used the original
speed sensor and control on the turn signal stalk. It took about a half a
day to install and a couple of runs down the highway to get the sensitivity
set the way I like it. It has worked great ever since. Make sure the servo
has a good ground. Being electric it draws more current than the control
valves in the vacuum unit.

Jim:
Thanks, that explains it. I'm pretty sure mine had a leak in the
diaphragm. If it didn't before I disassembled it, it definitely does
now! I'm not sure the vacuum generators I have sourced have that
self-control shut off feature. Did you use the Rostra Global Cruise
as a replacement? How is the servo operated on that unit and how long
did it take to install it?

Another vacuum generator question - davidkerryedwards - 09-13-2006 14:07
Thanks. If I can't find an acceptable vacuum generator replacement (which looks
unlikely
at the moment since I haven't been able to find a self--regulating one which
shuts off
once vacuum is adequate)I'll go with a global cruise.
