If I recall this is a vacuum operated system. Start by checking vacuum
connections. This symptom can be caused by a bad check valve or servo
diaphragm. A vacuum reservoir may also be needed due to the Vanagons low
manifold vacuum.

Subject: troubleshooting Audiovox Cruise Control

hello, I have one of the usual aftermarket Audiovox cruise controls on my 86
with AT.  I think it's model CCS-100?  I use the magnet speed sensor kit on
my drive shaft.  It's not working well.  It engages briefly and then
immediately disengages.  It will then attempt to resume to that speed if I
press that button, but immediately disengage.  That makes me think that it
is at least remembering the speed I set it to.  I've gone through the
troubleshooting of all the wires as the instruction manual specifies, and
everything is good.  I'm wondering if I could devise some way to monitor it
from the driver's seat to figure out what is going on.  Thanks for any
advice.

Edward
