Normal drain is around 25 mA, that is, .025 amp. A brake or tail light bulb will not illuminate on that current.

WES84: Chrysler calls that light the "Charging System Warning Light", I don't know just what triggers it, but I DO know that if your belt breaks and the systems "sees" that the alternator is not charging, the light comes on.

I strongly suspect your alternator is bad. I know you had it tested, but all WE can go on is what little we HAVE to go on.

As has been pointed out, putting a bulb in series iwth the battery cable (or better a milliammeter) will tell you just what current drain you have.

You can do a BASIC test of the alternator yourself, with a cheap voltmeter from Radio Shack, Lowes or Autozone:

1) With the car off, measure the voltage across the battery, is SHOULD be 12.0 volts, maybe as high as 12.7, etc.

2) Start the car, even at idle, the alternator should be able to raise the voltage across the battery to 13.8 volts, perhaps as high as 14.2 or so.

If you see NO increase, the alternator is not charging. If you only see a 1/4 or 1/2 volt rise, the alternator is only BARELY charging.

If you see the voltage rise to 13.6 or higher, the alternator is charging and the problem is likely something in the car draining the battery. If this is the case, see post four:

Be aware that something in the car draining the battery when parked will NOT light that "Battery" light.
I'd bet money you have a bad alternator.
