Tuffy Grand Rapids (Fuller Ave) Automotive Tips: Alternator

April 30, 2023

Your alternator makes electricity to start and run your engine and all of the vital electrical systems in your vehicle. That’s everything from the on-board computers to the turn signals. And of course there is the entertainment system, seat heaters, power windows and everything you plug into the power outlets. After your alternator makes enough electricity to do all that, it recharges your battery with what’s left over.

When Grand Rapids drivers constantly have a low or dead battery, the alternator is usually a prime suspect. However, the alternator is just one vital component of the starting/charging system, and a problem with any of the other components could be the actual cause.

In addition to the alternator, the charging/starting system includes the battery, starter, serpentine belt system and all of the electrical cables that connect them. Your Tuffy Grand Rapids (Fuller Ave) service advisor has a systematic process of testing components and connections to get to the source of your trouble. The initial symptoms determine where to begin the diagnostic process, and he follows the procedure until he tracks down the culprit.

For example, diagnostic tests at Tuffy Grand Rapids (Fuller Ave) could reveal that the alternator is not generating enough electricity to keep the battery charged. Is the alternator bad? Not necessarily. A worn serpentine belt tensioner could be allowing the belt that spins the alternator to slip. So the perfectly good alternator is not spinning at the proper speed. The solution for Grand Rapids drivers is to replace the serpentine belt system – not the alternator.

The good news for Grand Rapids drivers is that our highly-trained technicians at Tuffy Grand Rapids (Fuller Ave) can properly diagnose all your vehicle troubles and make the necessary repairs to get you back on the road in Grand Rapids.
