Diesel generator is not what is the reason for generating electricity
the excitation winding wiring error, polarity opposite.
the contact between the exciter brush and commutator is bad or the brush holder pressure is not enough.
damage to the circuit or circuit breaker, short circuit or grounding.
Diesel generator shutdown often lose remanence is used due to the exciter pole material close to steel, remanence, after stopping in the excitation winding is not current magnetic field disappeared.
