The alternator is an essential component of a car’s electrical system. It is responsible for charging the battery and powering the electrical accessories while the engine is running. A bad alternator can cause various issues, such as a dead battery or dimming lights. So, can you jumpstart a car with a bad alternator?
The short answer is yes, you can jumpstart a car with a bad alternator, but it’s not a permanent solution. Jumpstarting a car with a bad alternator will allow you to start the engine and drive for a short while, but once you turn off the engine, the battery will not have enough charge to start the car again.
How Jumpstarting Works
Jumpstarting a car is a temporary measure to provide enough power to start the engine.
- When you connect jumper cables between a good battery and a dead battery, the good battery supplies power to the dead battery.
- The electricity from the good battery gives the dead battery enough charge to start the engine.
- Once the engine is running, the alternator takes over and starts charging the battery.
Jumpstarting a Car With a Bad Alternator
Jumpstarting a car with a bad alternator works the same way, but you need to keep the engine running for as long as possible to prevent the battery from draining completely.
Here are the steps to jumpstart a car with a bad alternator:
- Ensure both cars are turned off and the jumper cables are untangled.
- Connect the positive (red) jumper cable to the positive terminal of the good battery.
- Connect the other end of the positive jumper cable to the positive terminal of the dead battery.
- Connect the negative (black) jumper cable to the negative terminal of the good battery.
- Connect the other end of the negative jumper cable to a metal part of the engine block or vehicle frame of the car with the dead battery.
- Start the engine of the car with the good battery and let it run for a couple of minutes.
- Try starting the engine of the car with the dead battery. If it starts, keep the engine running.
- Disconnect the jumper cables in the reverse order of how you connected them.
