Have the alternator bench tested for faulty rectifier diode pack
it may be charging the correct voltage but it is AC voltage and not DC voltage
in which case the battery will die quickly
next to check is the voltage regulator
it has to be 4.5-14.8 volts DC and if it in the ECM unit , will require a new ECM to fix
SOURCE: I have a 2001 PT Cruiser. The battery light came
Is it a remanufactured alternator. It sounds like you either got a faulty alternator or a wire is hooked up incorectly to it. I would test the voltage on the new one to make sure it wasnt a lemon If you are sure the wires are hooked up correctly.

Change the coil pack if your getting No spark.Or the crankshaft sensor.
