Like 3-way switches, don't go by the position of the terminal on the device's body, read the terminal labels. Like shown in all of the pics posted and linked here, the two input terminals are marked " ~ ", the positive output " + ", and the negative " - ".When I am testing the brigde but putting meter leads across the input of the bridge (opposide sides of diamond) I am seeing a low impedance one way and high impedance when the meter leads are swapped.
A continuity tester should show open with one lead on the + to each of the ~ 's in one direction, and continuity in the other direction, and the same results, but with the leads reversed, with the one lead on the - to each of the ~ 's.
