Where did you figure that 1/2 a volt? The positive side has battery voltage from E-box fuse (these are activated when DME relay is activated on ignition pos. 2) and a swithed ground from DME. When DME activates that ground solenoid opens a route for vacuum bell to pull the rod. If there is no vacuum obviously it won't work.
