quick question; should there be voltage coming out of the ammeter on the negative side?


I believe so...

Voltage is potential, volt meters have infinite resistance...

Ammeters measure flow and are supposed to have no resistance... Any resistance will slow down the flow... You will see a voltage drop across a resistance... Since amps is flow, there should not be any voltage drop...

Voltage is pressure, amps is flow...

(at least that's how I understand it...)
