3 Tips to Help You Handle a Battery Indicator Light
Electrical power plays an important role in the function of modern automobiles. The battery and alternator are the two primary components that work together to generate electrical energy. The battery stores the electrical energy created by the alternator, and this energy is used when starting your vehicle or powering accessories while the ignition is off.
If the battery indicator light is illuminated on your vehicle’s dash, this could mean that your car is running solely on the electrical energy stored inside the battery.
Don’t ignore your battery indicator light. If you don’t have an experienced mechanic diagnose the problem immediately, you may find yourself stranded on the side of the road with a vehicle that won’t start.
1. Complete a Charge System Check
The first thing you should do when you see your battery indicator light illuminated is complete a charging system check. This check will allow you to determine the status of your vehicle’s charging system.
Each time you move your key between the on, off, and run positions in the ignition, the charging system runs a self-check. You will see the battery indicator light illuminate for a few seconds while this self-check takes place.
If the charging system is working properly, the light will turn off automatically after a few moments. If the light remains illuminated, then the charging system has detected a problem that will need the attention of an experienced mechanic to repair.
2. Conserve Electrical Energy
Once you have determined that the battery indicator light is staying illuminated, you need to immediately conserve any electrical energy in your vehicle. This means turning off all non-essential accessories that are powered by the charging system.
Don’t use your air conditioner or heater. Turn off the radio and make sure all interior lights are in the off position. Disable your headlights if you are driving during the day. Unplug your cell phone from its charger.
By cutting the power to these accessories, you can reserve as much electrical energy as possible to power your vehicle’s engine. This will allow you to drive to your local repair shop safely before your vehicle completely runs out of electrical energy and the engine dies.
3. Check Your Temperature Gauge
You might not think that your charging system and the temperature inside your engine bay are related, but problems with the alternator can spell disaster for your vehicle’s engine as a whole.
The alternator and water pump share a belt in many modern vehicles. If the alternator (a critical component in your charging system) is no longer working, the belt on the water pump might not be working either. This will cause the water pump to shut down completely.
The water pump circulates cool liquid throughout the engine bay to help keep operating temperatures low. A temperature gauge on your dashboard will allow you to monitor the engine temperature at all times.
If you see the temperature gauge rising or notice that the temperature light is illuminated on your dash along with your battery indicator, stop driving your vehicle immediately. The continued operation might cause your engine to overheat, resulting in irreparable damage and the need to replace the engine along with any malfunctioning charging system components.
The battery indicator light serves a valuable purpose in helping you maintain the safety and performance of your car. You need to know what to do if the battery indicator light in your vehicle turns on so that you can avoid causing additional damage to the mechanical components in your car.
