Alternator overcharging? Here is How to Fix it

Have you ever face an alternator overcharging problem? Worrying is not needed. It’s not that hard to fix this issue at all.

Let’s find out;

What is an alternator overcharging?

An alternator overcharging is the production of excess voltage to the battery. The battery case swells up and becomes very hot. As a result, this causes the loss of its electrolytes through boiling.

This escalation disrupts the wiring in the alternator, which results in overcharging.

Now, as batteries and alternators are the backbones of a vehicle’s electrical system, they produce electricity from mechanical rotational energy. Their care is a prime priority in any vehicle.

The alternator is the part of your vehicle that provides a constant charge to the battery. It is a vital part that is the source of energy for the whole mechanical body.

why is my alternator overcharging?

There are many reasons for an alternator to start overcharging. Here I’m listing a few common reasons for you to get an idea of what might be wrong with your alternator.

High Gauge Reading

It causes the voltmeter on the vehicle to read high voltage may not vary with engine speed. Normal readings are high upon start-up, then settle in the normal range. It causes the meter to stay in a high position after start-up.

Low Battery Electrolyte

Low battery electrolyte level signifies that the alternator is overcharging the battery, which results in heat generation and causes the electrolyte to evaporate.

Burnt Bulbs

An overcharging alternator leads to headlights and tail lights blowing out. Other burnout symptoms of an overcharging alternator include blown fuses, dash, and interior lights blowing out and light becoming extremely bright when engine speeds up.

Battery Heating

Overcharging of the battery by malfunctioning alternator results in the battery’s overcharged state. When overcharged, the plates inside the battery shed material resulting in loss of capacity to hold electricity. The battery resists further charging, which causes the electrical charge to build up.

How to stop the alternator from overcharging?

Here are a few ways to prevent damage to the alternator following precautions will help

Solution 1: Choose the right belt

The key to an alternator’s long life is to keep examining the belt from time to time. Because it is made of rubber, so it may wear off or crack with time. Keep checking and replace when the first signs of damage appear.

Solution 2: Clean any dirt or dust

Keep looking for signs of dust or dirt on your alternator. Try to keep it clean from time to time so that air may keep passing through it. Otherwise, it will coagulate with dust in time, and then it’ll overheat.

Solution 3: Keep it aligned

From traveling, the car experiences jolts which may result in the pulleys and the alternator displacement. Make sure they are aligned to work and prevent overcharging.
