What Causes an Alternator to Not Charge? – Tips and Diagnosis

Hi-ya! good afternoon, now we will write an article about What Causes an Alternator to Not Charge? – Tips and Diagnosis

Your vehicle may be experiencing alternator problems if the battery is constantly draining; but when you have the battery checked for problems, it maintains a consistent charge. It is already a problem in the alternator, that is why here you will learn what causes an alternator not to charge.

The alternator is the part of the car responsible for keeping the battery charged. If your battery is not recharged by the alternator while the vehicle is being driven, the battery will eventually run out of power and your vehicle will stop working.

What causes an alternator not to charge

There are several different problems that can cause your alternator to stop working.

1- Pulley and Belt

Your vehicle’s alternator charges the battery by generating power with a pulley and belt system. If the belt that controls that system stretches or breaks, the alternator will stop working and the battery will not charge. The same will happen if the pulley gets damaged, shifts, or for whatever reason malfunctions and no longer turns.

2- Wiring

The alternator is powered by several different wiring mechanisms. If a wire is not connected properly, comes loose, or is inadvertently cut, the alternator will not have power. If the alternator is not receiving power, it cannot turn the pulley and belt mechanism that charges the battery, and the battery will not charge.

3- Fuses

Some vehicles have a specific fuse for the alternator. If this fuse blows, either due to age or a surge in the vehicle, the alternator will not work until it is replaced. Check your vehicle’s fuse box diagram to determine if your vehicle has a fuse for the alternator.

4- Computer problems

On many newer car models, specifically those made since 2000, the alternator is controlled by the car’s computer. If your vehicle’s computer is malfunctioning or having system problems, it may cause the alternator not to charge.
