3 Common Alternator Problems, De Kalb, Texas

The alternator is responsible for supplying energy to your engine’s battery to ensure it stays charged. Because it has such a crucial job, you’ll quickly notice if something’s gone wrong with this part. Identifying the problem is the first step in getting yours back in working order, so look out for signs of the following issues.

What Can Cause a Malfunctioning Alternator?

1. Worn Belt

Alternators work by creating an electrical current that flows back and forth, and this current is produced by several components spinning. The serpentine belt is essential to keeping these pieces in motion.

If your belt is worn out, loose, or slipping off of its track, your alternator won’t be able to charge the battery. Worn belts may have chunks missing or shiny spots, and they sometimes make a high-pitched noise when the motor is running.

2. Improper Battery Connections

Make sure that the cables are fastened snugly and clean excess dirt and grease off of them. Double-check that none of the cables or terminals have any damage. Also, take a look at the connections to the voltage regulator, which is the part that turns the alternator on and off.

3. Overcharging, Undercharging, or Not Charging the Battery

If the battery isn’t being charged enough, or if it’s being charged too much, your vehicle won’t maintain the proper power level. This will result in noticeable problems like dim lights and malfunctioning temperature regulation systems. You can check the manufacturing details of your vehicle to find out what level the voltage should be at and compare it to the flow of power to the battery.
