I have a 95 Sahara with Cummins B-230 engine.
Maybe someone can point me in right direction or to some someone who can help.
I have the Rostra Precision Controls Inc. Vacuum Cruise Control system.
It just shut it self off on the last trip and would not reset.
It has done this before but had always reset.
I checked the vacuum pump and it seems ok.
I called Rostra Precision but the tech said they had not made the system since 1991. He was not trained on it and there are no part available to his knowledge. (My impression was that he was probably in grade school when the last vacuum CC was built by Rostra)
I do have a generic WD for Safari MHs.
