#1 Dimming Lights

The primary function of the alternator is to help your battery maintain its charge. If this isn’t working properly, the engine may begin to lose power while driving. One of the key signs that the alternator is not charging the battery properly is dimmed lights. The headlights or interior lights of the vehicle may dim periodically or stay dimmer than usual.

#2 Warning Lights

Modern cars have dashboard warning lights for just about everything. The little battery shaped light doesn’t mean your battery suddenly died. You need your battery for that light to come on. It usually means there is a problem with the alternator. The battery may be growing weak because the alternator isn’t helping it charge properly

#3 Signs of Low Power

There are also other indicators that your car is suffering from a lack of power. Electric windows may open and close slower than before. A power seat may move slowly. Basically, the electrical components all seem underpowered. Once the car begins to lose power, it won’t be long before the alternator gives way completely. That means even a fully charged battery won’t be enough to keep the car running.
