When the starter motor starts under load?

When the starter motor starts under load, it experiences increased resistance as it attempts to turn the engine, which can lead to higher current draw and a greater demand on the battery. This condition can cause the battery voltage to drop, potentially resulting in sluggish cranking or failure to start if the battery is weak or if the starter motor is faulty. Additionally, prolonged cranking under load can generate excessive heat in the starter motor, leading to potential damage or burnout. Proper maintenance and ensuring a healthy battery are crucial for optimal starter performance under load.
