How to Determine if a Car's Starter Motor is Faulty?

[LaJohnny]

Methods to determine if a car's starter motor is faulty: If the battery voltage is sufficient but the engine cranks weakly or does not respond at all, and it only starts after tapping the starter, this indicates that the starter motor is faulty. The solution is to jump-start the battery. If the engine still cranks weakly, the owner should have the starter motor inspected or replaced. The starter motor is an electrically driven device mounted on the engine, used to start diesel or gasoline engines. It eliminates the hassle of manual engine starting, offering quick, reusable, and widely applicable operation. How a car's starter motor works: The starter motor converts the battery's electrical energy into mechanical energy, driving the engine's flywheel to rotate and initiate the engine's start. The starter motor consists of three main parts: a DC motor, a transmission mechanism, and an electromagnetic switch.
