Truly the one other elements that could be undesirable might be the rotor and stator. These can idiot your ohmmeter check, because the resistance amongst The three wires on the stator as well as two slip rings about the rotor is rather close to zero. There can be a brief concerning coils, as well as examining would also be zero.
