——The left chart is QDY1258
——When checking starter, you should clean
carbon brush. Its surface should not have dust
and calibrator, and the brush can move freely in
the carbon brush carrier. Change them if the
brush and carrier are damaged severely.
——Clean the commutator’s surface with clean
cloth. And engage the commutator if its surface
is not smooth and round.
——As assembling carbon brush, make sure
the brush spring is pressed on the brush
correctly.
——Pay more attention to keep the wire
bayonet clip clean. Make sure there’s no oil
fouling and water. Or the voltage drop is too
high, and the engine doesn’t work.
