Common faults and solutions of starter

2022-10-20

First, the driving gear of the starter does not rotate and cannot work normally. There are many reasons for this, such as battery damage, insufficient kinetic energy, damage to the circuit from the battery to the starter, ablation of the starter switch contact plate, excessive engine resistance, or direct damage to the starter.

When this happens, we need to make a preliminary diagnosis of the cause of failure to start, and then deal with it accordingly. If the circuit is damaged, repair the circuit; If the battery is damaged, replace the battery. If the contact plate of the starting switch is ablated, the engine resistance is too high, or the starter is directly burnt out, it needs to be handled at the corresponding maintenance point.

Second, the power output of the starter is insufficient to drive the crankshaft. This situation indicates that the starter is moving, but it moves slowly and cannot drive the crankshaft. Most of the reasons are short circuit of excitation coil and lack of battery power, which will cause insufficient starter power, and we can deal with it accordingly.

3. After the start switch is turned on, the starter rotates at high speed and the engine cannot be started. The reason for this is mostly in the transmission mechanism, which may also be caused by the wear of transmission gear or one-way clutch.

4、 The starter makes a harsh noise. This may be caused by the one-way clutch being stuck or the starter being improperly installed.
