Installation and Maintenance

Proper installation is vital for the longevity of the starter motor. Before beginning work, ensure the battery is disconnected to prevent short circuits. During installation, pay close attention to contact cleanliness and tighten mounting bolts securely, as engine vibrations can loosen connections over time. Regularly inspect power cables and battery health, as a weak battery is the most common cause of starting issues, rather than a failure of the starter motor itself.
