Listers -
As background, I have recently installed an alternator and pertronix ignition
system in my late model BJ8. There are no other bells or whistles on the car.
I am now in the process of installing the Rostra 250-1223 Cruise Control unit
along with the 250-3592 switch and 250-4165 signal generator. I have followed
the wiring and installation directions very carefully and everything seems to
work fine except the car "surges" when the cruise is engaged. I have tried
several "switch" changes to tune the throttle control but it still surges when
engaged. By "surge" I mean the car will speed up to the set speed, then coast
for about a second and then surge back to the set speed over and over again.
I have talked with the tech folks at Rostra several times but can't seem to
find a solution. They tell me it is my car to blame. The latest suggestion
was to ground the unit directly to the negative side of the battery, I presume
to avoid electrical interference. I did this, but no change. I did not
ground the control switch to the battery, just the cruise module; could this
allow the interference I'm trying to avoid?
Any suggestions or the contact information of someone in the "know" about
these units would be greatly appreciated.
