What Does the Alternator Do?

The alternator is an integral part of your car. So, what does an alternator do? It generates power when the engine is running. This power recharges the battery and operates other electrical components, like the lights, radio, and air conditioning. When the ignition is off, the battery provides power to start the engine and run electrical devices. Once the engine is cranked, the alternator takes over, charging the battery and supplying power to the car’s systems. If the alternator isn’t working, the battery will eventually run out, and the car won’t start.

Signs Of A Bad Alternator

If you think your alternator might be failing, look for these common signs of a bad alternator:

• Dimming lights – If your headlights or dashboard lights are dim or flicker, it could mean the alternator isn’t working correctly.
• Battery warning light – If the battery warning light on your dashboard lights up, it could indicate a problem with the alternator.
• Strange noises – If you hear grinding or whining noises from the alternator, it may fail.

Can You Jumpstart A Car With A Bad Alternator?

Yes, you can jumpstart a car with a bad alternator, but there are some important things to keep in mind: how to know if your alternator is bad. If your car starts but dies shortly after, or if you notice dimming lights and strange electrical issues, these could be signs of a failing alternator. While jumpstarting might get you moving temporarily, it won’t fix the underlying problem with the alternator.

• Temporary fix – A jumpstart can help you start the engine for a while, but it won’t recharge the battery if the alternator isn’t working. The battery will run out of power again, and the car will stop.
• Checking the problem – If your car starts after a jump but then dies again quickly, it’s a sign that the alternator is the issue. You might need to have it checked by a mechanic.
• Battery condition – If your battery is old, it might not hold a charge even after a jumpstart. It’s essential to check both the battery and the alternator.

How To Jumpstart

Jumpstarting a car with a bad alternator can be a straightforward process if you follow the proper steps.

• Gather equipment – Begin by gathering the necessary equipment, which includes jumper cables and another vehicle with a working battery.
• Position the cars – Position the cars close enough so the jumper cables can reach each other, ensuring that the vehicles do not touch.
• Connect the cables – Start by connecting the red cable to the positive terminal of the dead battery, and then connect the other end of the red cable to the positive terminal of the working battery. Next, take the black cable and connect it to the negative terminal of the working battery before attaching the other end to a grounded metal surface on the dead car.
• Start the working vehicle – Once the cables are securely connected, start the working vehicle and allow it to charge the dead battery for a few minutes.
• Attempt to start the dead car – After a few minutes, try starting the car with the bad alternator to see if the jump is successful.
• Let the engine run – If the jump works, allow the engine to run to utilise any remaining battery power effectively.

What To Do If The Alternator Is Bad

If you find out that your alternator is not working, here are some steps to take:

1. Replace The Alternator

The best solution is to have the alternator replaced. This will allow your vehicle to generate power and keep the battery charged.

2. Check The Battery

If the battery has been drained multiple times because of a faulty alternator, it might need replacing.

3. Get Professional Help

If you are unsure about diagnosing the problem or replacing the alternator, ask a professional for assistance.

4. Regular Maintenance

To avoid future problems with your alternator and battery, regular maintenance is important. Check the battery and alternator often, especially if you notice warning signs.

Conclusion

In conclusion, while you can jumpstart a car with a bad alternator, it is only a temporary solution. The alternator is crucial for keeping the battery charged, and if it’s not working, the vehicle will eventually stop again. Knowing the signs of a failing alternator can help you act early and avoid getting stranded.

If you suspect your alternator is bad, getting help from a professional mechanic is best. Replacing it will ensure your vehicle runs smoothly and efficiently. Contact us today to book an appointment.
