Would a bad alternator on 1999 Grand Cherokee Jeep Limited keep discharging brand new battery?

Yes, a bad alternator on a 1999 Jeep Grand Cherokee Limited can definitely keep discharging a brand new battery. Here's why:

* The alternator's job: The alternator is responsible for charging the battery while the engine is running. It provides power to the electrical system of the vehicle.

* A faulty alternator: If the alternator is faulty, it won't be able to generate sufficient charge to maintain the battery's level. This means that even a brand new battery will slowly lose its charge while the vehicle is running.

* Symptoms of a bad alternator:

* Battery light on the dashboard illuminating

* Dim headlights, especially when the engine is running

* Difficulty starting the engine

* Electrical components failing to work properly

How to check if your alternator is bad:

1. Battery voltage test: With the engine running, check the battery voltage with a voltmeter. It should be between 13.5-14.5 volts. If it's significantly lower, it's a strong indication of an alternator problem.

2. Load test: While the engine is running, turn on headlights and other electrical components. The voltage should remain above 13.5 volts. If it drops significantly, your alternator is likely failing.

Important Note: If you suspect your alternator is bad, it's crucial to get it checked by a qualified mechanic as soon as possible. Driving with a faulty alternator can lead to serious problems, including a completely dead battery and potential damage to other electrical components.
