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

=== === Some types of electrical shorts do cause the battery to discharge. But usually a bad alternator just does not charge the battery. Or does not put a large enough charge back into the battery. This causes the battery to discharge when you start and run the motor. The spark plugs and other things need electricity that would usually come from the alternator is now coming from your battery. If your bad alternator is not recharging the new battery, the battery will soon fail to start or run your vehicle. You need to have your alternator tested. It should be putting out at least 12 volts, usually around 13 to 15 volts.

How can I test my alternator to see if it is discharging my battery?
You can have the alternator tested free of charge at just about any major auto parts store. By the way, a bad alternator will not "discharge" a battery - the alternator's function is to provide the charge to the battery. If the alternator is faulty, then it is not providing the charge necessary to keep other components from discharging the battery. I had the alternator tested and it was charging. If the alternator has a bad diode, it will discharge the battery. I replaced the alternator and everything is fine.
Clock keeps reseting in a 93 Jeep Grand Cherokee limited?
If the clock keeps resetting in a 1993 Jeep Grand Cherokee Limited, the problem is probably with the battery. It is quite possible that the battery is going dead after the vehicle is parked, leaving just enough life in it to restart the car. It can also be an alternator problem causing the battery to be drained.

Does a dead battery cause the alternator to not work after it is charged?
A battery is nothing more than a storage device for electric power. The alternator changes the kinetic energy given off by the engine into electrical energy. If the battery can be charged and store energy but the battery keeps discharging after you use the vehicle, check the alternator. If someone accidentally reversed polarity EVEN BRIEFLY while jump-starting the vehicle the diode plate is probably destroyed and you will have to replace or repair the alternator.
