Why does my amp meter read the same amps on the negatave combiner as it does on the positive combiner. Thank You

    The current flow is through the entire circuit, a closed loop, so it will read equally on both legs.

    Having the negative connected to the ground will  have no effect  on the circuit  as the positive is isolated from the ground and negative.
