FIST U WILL CHEK THE HP RATHIG THEN NEXT CHEKED AMPS

Answer / loboreliance2003

The motor drawing 1.6A on no load appears to be okay.The
motor drawing 4.8A on no load appears to have a fault. the
winding may be having not proper megger value. Or even
rewinding of this motor may have been done improperly. You
will not find this condition in new motors from original
manufacturer.
