Am I not understanding this correctly?

As I said it should be zero.
Read the voltage from A to B and from A to D. They should be the same and half the voltage from A to C.

Correct! The voltage should be zero if all the strain gauges have equal resistance and there is no stress.
To test for continuity you should read 2.5 volts from zero volts to the white wires on both sides of the bridge.

I completely understand now Sghioto. I overcomplicated things throughout; it's actually simple. I should've only used two wires instead of three wires because three wires only helps when it's a quarter bridge and not a full bridge, but I think I'm going to leave it like this since I can still get the correct answer.

Again, thank you for you help. Very much appreciated
