Electrical Issues

Alternators are critical components of a semi's charging system since they supply power to the battery.  If the warning lights on your dashboard illuminate, this could indicate an alternator problem. Dimming or flickering headlights or interior lights may also indicate that the alternator is not delivering enough power. A faulty alternator is also indicated by a weak or dead battery, as the alternator is responsible for charging the battery while driving. 

Difficulty Starting the Engine

When you experience extended cranking or slow engine turnover, it is usually due to an insufficient power supply from the alternator. A faulty alternator fails to effectively charge the battery, leaving it depleted and unable to produce the necessary energy to start the engine. Ignoring this early red flag may result in inconvenient breakdowns and downtime. 

Strange Noises

Defective alternators usually generate loud, unusual noises. The alternator receives mechanical power from the engine via a belt. You may hear squeaking from under the hood if this belt is out of place or worn down. If the alternator belt wears out, it may not spin fast enough to provide enough electricity. In conjunction with the belt, the alternator's bearings enable the internal stator to rotate. As they rust and deteriorate, these bearings begin to hum. As the bearings degenerate further, the noise becomes louder.
