Your Alternator is toast. Or check the plug that connects to the back of te alternator, its a gray plug with 2 wires that go into it. Sometimes the inside of that plug will break apart (it's plastic). Happened to me 2 times.

Alternators are about $120 at the part store, or I got a used one for $40 + shipping... we will need to verify the plug on the back of yours though because there are 2 different plug styles.

If it's sitting for 2 days, and not driven or started and the battery is dead... That means the battery is defective. If its a newer battery, find out what the warranty is because it is possible to get a brand new battery and it be defective.

You need to check for a short if its draining just sitting. Never in my neon but a couple other cars I had did this. Twice the alternator was shorted and the other time it was a shorted headlight switch. A short can cause a constant drain on the battery. Charge the battery and leave it disconnected to see if the battery is toast. I never checked for a short on my neon but you used to be able to pull the negative cable off the battery and hook a test light up between the negative post an negative cable. If the light comes on you had a short, start pulling fuses until the light goes out, if it didnt go out unplug the alternator and see if that killed the short. This may or may not work on cars nowadays.
