Q: Please help me diagnose an electrical drive by wiring

asked by on

I performed pin by pin test on wiring according to manufacturers service manual, I have two seemingly ambiguous results, the first is 50.7 ohms of resistance in the F terminal of the APP wiring terminal and the main relay terminal A. I attributed this to the evap leak detection pump which shares this wire since that is at the top end of normal resistance between power and ground (terminals A & B) for that component. Is this correct? Secondly in the manufacturers (mazda) manual it refers to continuity between the ground terminal and the power supply of both the APP and the Evap leak detection pump as a short circuit. Isn't that a complete circuit and totally normal?
My car has an automatic transmission.
