When the starter motor rotates without force (that is, it can rotate when decompressed, and stops immediately after it is compressed or rotates without force), it is not only related to the technical state of the motor itself, but also related to how much battery power is stored and the contact condition of the connecting line. Two types of fault location determination are now introduced. method. Before the lighting method is started, turn on the two headlamps, start the motor rotation, observe the light changes. If the light goes out immediately or the filament turns dark red, the battery is not fully charged. If the brightness of the light does not change much, it means that the starter motor has a fault; if the light is dimmed, smoke will occur at the starter motor, which means that the battery has insufficient power and the starter motor has a fault. Observe and listen to the sound method (1) When the engine is depressurized, the motor rotates smoothly and the sound is normal. After the compression, the motor will not turn or rotate quickly. This is caused by insufficient battery storage. (2) When the engine decompresses, the motor rotates slowly and the commutator emits a strong spark. After the compression, the motor does not rotate or rotate. This is because the commutator is out of round, the mica protrudes, the carbon brush is excessively worn, the contact pressure is insufficient, or the armature coil is insufficient Partial open circuit, short circuit, iron touch caused. (3) When the engine decompresses, the motor will rotate slowly or smoke, and immediately after compression, it will not rotate or rotate, indicating that the motor is partially damaged by insulation or the broom.
