What causes abnormal noise from the starter when starting the vehicle?
1 Answers
When starting the vehicle, the reasons for abnormal noise from the starter: 1. The main contacts of the electromagnetic switch engage too early: The starter makes abnormal noise when the starter drive gear has not yet meshed with the flywheel ring gear. 2. Poor contact of the electromagnetic switch: The rotor collides with the magnetic pole, the brushes are excessively worn, or the electromagnetic switch has poor contact. 3. The drive gear fails to disengage: The drive gear does not disengage and continues to operate. After turning off the ignition switch and cutting off the power, the starter still runs. A screeching sound occurs immediately after the engine starts. The starter is dragged backward at high speed and cannot stop, or it takes a long time to stop, causing the starter to sweep and burn out.
