Hitachi utopia fault code 39

[n1redrum]

Hey, having real proplems with a hitachi utopia heatpump single phase. Initially the condensing unit had been tapped by a truck and lost its gas, so repaired and regased. but now error code 39 keeps coming up (overcurrent) so checked the amps to the comp which is fine, so is the current transformer. Then thought maybe a blockage in the system or overgased, so reclaimed and blew nitrogen through (no blockage) then tried running the comp (single phase) unpiped and pressure switches over ridden but power is still tripping to the contactor stopping the compressor. everytime i reset on isolator comp runs for about 3 seconds and then this happens. im a little stumped so any links or help would be apprieciated.
