I'm assuming your referencing pin 7 of the lower connector. If so, your seeing a point of resistance in the ground circuit. Pin number 7 is connected (internally) to the bottom Ignition Control Module Mounting holes and these metal mounting holes are the source of Ground to the engine block (see photo 3 of 3 in the image viewer of test two). Ensure all surfaces are clean and all mounting screws are present and tight. Additionally, check the engine block and chassis to battery ground connections are good.
