Help.
MY 82 c3 has never had an operating cruise control. The switch seems to work work via tester and the servo holds vacum. I did install a new transducer also. All hoses are going to the right areas.
There is a small solenoid on the top of the transducer that someone mentioned that it is part of the resume system. I know that I'm getting good vacuum to the solenoid but I'm not sure if it passing through the solinoid.
Suggestions please?

Boy - I remember unplugging the connector and turning it 90° and plugging what was the vertical female on the horizontal male spade. Key on and pushing the set button, if I heard it clicking the set switch and resume solenoid was OK.
Then I went to the brake switch, found the vacuum dump the problem most of the time

Hi again.....I had to take a break from working on the vet to work.
Now I Habs time to continue with my cc problem.
I have check all of the electrical connections from the switch to the cc unit a day all is well. I have replaced the brake switch too. I noticed that when I was checking the engage button, my tester showed a pulse for a connection. Not a constant on. Is this right?
Is there a way to check the transducer itself?
Still no cruise.
Thank you

The cruise control also uses a switch on the brake pedal that will disengage the cruise control when the brake pedal is depressed. It's possible your switch has been disconnected or removed by a previous owner.
 
Thank you for the reply.
I did replace the switch with the electrical contact for the disengage. I checked it and it is properly working through the wiring diagram. Now I'm checking the cruise brake release valve. I ran a vacuum check and it seems to lack the ability to hold pressure.
I'm looking to replace this next.
I am looking for a resistance measurement for the transducer if anyone could help with that please.
Thank you

The issue is usually the transducer. Do a search here on this forum as I posted my own corrective solution which may help you get your cruise to work again.

My diaphragm failed about 20 years ago and I never bothered to replace it. First of all a replacement cost about $100 and secondly I never liked to use a cruise control anyway. I would much rather have full control over my throttle all the time and if my foot gets a little tired on a long trip I just stop for a while and walk around. Take a leak, buy some snacks, stretch my arms and legs, and enjoy the moment. When I travel I have always felt it's better to drive slowly and enjoy the sights.
 
Bingo on the cruise brake release valve. I now have cruise control.
Thank you everyone

The switch was physically there. The vacuum side of the switch leaked and the electrical contacts created a short.
The unit looked original from 82
