Battery Light On and Off While Driving

The battery warning light indicator on dashboard is occasionally on and off while driving the possible reason is that the alternator is failing or the alternator belt is slipping.


Possible cause of battery light that flickers
1)The alternator belt is slipping.
2)The alternator itself is failing.

When the battery dashboard warning lights indicator flickers while the car is running there are two possibilities that causing this kind car trouble, as mentioned above it can cause by the slipping alternator belt or a failing alternator. The alternator is the device that provides electricity to the car battery, it is connected from the engine using an alternator belt, when the engine runs some of the power will be transferred to the alternator to make it runs and create electricity so that the battery will charge, aside from providing charges to the battery the alternator is also the one that provides electrical power to all your car accessories like the radio, air con, lights, etc. while the engine is running. Now, if the battery warning light indicator located on the instrument panel is lit “ON” then it means that the alternator is not generating electricity that the car accessories are needed.

Since the problem is the battery warning lights only flickers, sometimes on and sometimes off, then the problem is intermittently occurring which means that the alternator is sometimes generating electricity and sometimes not generating electricity or somewhat failing, during the time the alternator fails it cannot generates electricity and the battery warning lights is always on.
