Battery warning light: Five factors that might be responsible

04/06/2019

What do you do when your battery warning light comes on? Ignoring it is a bad idea. Find out possible reasons why the light is on and check them ASAP!

Warning light – the name itself is self explanatory. These lights give you signals about certain things to examine as they are on the verge of breaking down. When something is amiss in your car, the monitoring system sends a message from the source down to the dashboard which then voices the issue with the use of lights.

A number of equipment in cars have warning lights, and the battery is one of them. Upon starting your car, all the warning lights come on. Ideally, they go off after a few seconds. If you observe that the battery warning light remains on, it is an indication that it is not doing okay, and requires urgent attention.

1. What does battery warning light represent?

Your car needs adequate voltage to function. The moment you turn on your ignition, the system does a quick check to ascertain that enough voltage is being produced by the battery or the alternator. The battery warning light is on at this point. This happens really fast. If the system sees that the battery is giving off accurate voltage, the light goes off – an indication that there is no cause for alarm. But if the light stays on, it means that the coast is not clear. Your journey might have to wait as you need to check what the problem is. Failure to do this could lead to more serious problems.

If you are in a hurry to somewhere important, you can manage your car. But first, you need to limit the appliances in use so your battery’s power will not be drained completely.

2. Items to check when battery warning light comes on

2.1. Battery

Since the battery is acting up, it is only logical that you check it first before checking any other instrument in your car. A battery in good working condition normally has a green light on its icon on the dashboard. The green light turns to red when the battery is faulty.

A red light on the battery’s icon is a signal for overheating. In some cases, this is a cue for you to have the battery replaced as the current one has run out of capacity to be useful.

Check if the battery has power when the warning light comes on

Batteries come with instructions on how to determine their condition. You should take a look at the instructions on yours to draw your conclusions.

The battery connectors are areas you should also check. If these connectors are not sending the right signals, it is impossible for the battery to function well.

2. Alternator

The next suspect on the list is the alternator. There is no one-size-fits-all way to tell that an alternator is bad as different models react in different ways. Some alternators knock out when faulty. In this condition, they no longer produce the electrical power meant to charge the battery.

In the absence of the power needed from the alternator, it is understandable that the battery can no longer work. Depending on the degree of damage, you may have to fix it or replace it completely.

3. Regulator

The regulator plays a similar role to the alternator. It powers the battery with quick charges. With the regulator, the power produced has to be moderate. If it dishes out too much power to the battery, there is a problem. And if it dishes out inadequate power, there is a problem too.

The regulator is an extension of the alternator. To get maximum results, you might have to replace both of them so the problem from the old tool does not affect the newly replaced one.

4. Belt

Without the belt, the alternator cannot spin. The spinning is essential for it to generate sufficient electricity generated for the battery. When the belt wears out or breaks, spinning is suspended. And until it resumes, there is no electricity for the battery, hence, the shutting down.

5. Cables

Last but not the least items to check in your car engine when your battery warning light comes on are the cables. These cables work with the belt to spin the alternator in generating electricity transferred to the battery. They are at their best when they are firm. Loose cables do not exert adequate pressure required for spinning the alternator.

Fix the cables in the right places

Your first bet is to check if they are loose. If that is the case, all you need to do is tighten them. Check the part where they are connected to the battery. Are they in the right position? If not, fix them well. Cable wires can wear out or break due to excessive use. A replacement is needed in such a situation for a stronger spinning.

In the process of diagnosing the reason why the battery warning light is on, you should turn off car appliances such as air conditioner, headlights, radio and other gadgets that suck power from the battery. That way, you are able to identify the root of the problem accurately.
