Where was the meter's ground lead connected though all that testing? Remember, voltage is 0 with out a ground path. Leave the meters ground lead off and touch the pos lead to the battery B+ and see what the meter reads. This is where the term "voltage = the difference in potential" comes in. I would focus more on the ground circuit then the B+ circuit. I think you will probably find something.
