Please explain how there can be current when no load has been placed on the transformer??????????????
Surely,there can be no current,when there is no load on the transformer.If the 120V loads on the 120V/240V single phase transformer are not balanced,the voltages across them would also be unbalanced,should the neutral be broken.The OP reported that the voltages normalized on connection of X2 X3 to the ground.It means that in addition to broken neutral,there might be ground fault of neutral wire also.This could easily be ascertained by checking the current in neutral-ground connection.
