basically this type of problem created when motor winding delta coil sequence not proper. For finding of fault following this processor :- Firstly check motor winding continuity 1:5{RR} ,2:6{YY} & 4:3{BB} .if continuity not matched then interchanged sequence of {RR} wire of power .if problem not solved then again interchanged second sequence of {YY} wire of cable .
