With the solenoid disconnected I get 8psi of boost and that's it, so the problem appears to be with the solenoid. At least I can run without the solenoid without worrying about blowing up the engine. Yay!
I checked its connections, and they all look good, but who knows. What is the proper test procedure to verify that the solenoid is working? Just apply 12 volts and then it passes air? From that I should be able to verify if it's connected properly and trace the wiring to the Link. Thanks!
