Assuming the typical running amps for a normally-operating compressor of this size to be about 1.7 amps (typical), then an observed running current of 2.5 amps, while still not seeming like a lot of current compared to locked rotor current, represents a 47% increase in operating current draw! This is a big jump and indicates a serious degradation of the compressor motor. I'll bet if you put a megger on it, you'd find a high resistance current path from the motor windings to ground which would account for the extra current draw (and subsequent leakage to ground).
