What are the reasons for a weak starter?

[StGabriella]

The reasons for a weak starter are: 1. Insufficient battery power or loose, poor-contact connecting wires; 2. Starter bearings that are too tight or excessively loose; 3. Burnt contacts in the starter switch or short-circuited electromagnetic switch coils; 4. Open or short circuits in the series auxiliary coils of the armature-movement starter. The symptoms of a weak starter include: 1. The starter rotates slowly and weakly, making it difficult to turn the engine; 2. When the starter switch is engaged, the starter only makes a clicking sound and does not start. The starter, also known as the motor, converts the battery's electrical energy into mechanical energy to drive the engine flywheel and start the engine.
