1984 motorhome cruise control
I am trying to repair the cruise control using the factory service manual. The service manual states I should have a brown control box, mine is grey, I also have two additional wires going to the control box where the service manual says there should not be any, a couple of color codes did not match either. I did check the switches located on the turnsignal lever and they work as the manual states at the control box. I am not able to follow the rest of the manual since they use a special tester and a different color control box. I am now questioning the vacuum side of the cruise. The vacuum line from the engine goes to a red 2" X 2" valve. The outlet from the valve is a smaller vacuum line than the one from the engine and it goes to the servo. There is more vacuum going to the valve then what is coming out, which is probably the reason it is not working. Is it normal to have less vacuum? What is the purpose of the valve? Could I bypass this valve to obtain more vacuum at the servo? I could use some guidance.
