Hi,

just remember that current always flows in a loop. You should be able to model what would happen by including some ground impedance.

If the generator is referenced to the ground at the source, then you are likely to have some "ground bounce" at the load. The current itself will not change unless it is dependent on the load impedance.

regards,
Aaron
