Seriously the only other elements that may be bad would be the rotor and stator. These can idiot your ohmmeter check, since the resistance in between the 3 wires with the stator along with the 2 slip rings within the rotor is incredibly near zero. There can be a brief in between coils, as well as looking at would also be zero.
