Is the Bentley engine abnormal?

Hello, usually the following reasons: 1, the startup time is too long, and the starter is not used according to the specified time (about 5s ~ 10s), which leads to the use time of the starter is too long, and the reason is not found out.

2, when the brush wear to the original length 1/2, should replace the brush. When repairing the starter, check the height and contact of the brush regularly, and eliminate the problems in time if found, otherwise the starter will be scrapped.

3. The electromagnetic switch has poor contact, and the unidirectional teeth and flywheel teeth are damaged. Poor iron strike of the iron strike line and so on will cause the failure of the starter. You should go into the factory for maintenance as soon as you find that the startup is faulty. Thank you, Wang Cai.
