Default Charging problem/question

I recently replaced my alternator because my original sounded like an off key rap song (no offence). Since its replacement, my battery went dead. I though I had left the door open because after taking the car cover off a few weekends ago, I found the door wasn't totally closed. I then charged the battery and went on my way for a few weeks. I just came back from a weeks vacation to find my battery dead again. After some investigation I found something was drawing .3A with the car off and all doors closed. I decided to first remove the alternator since its the newest item and I never had this problem before its replacement. After removing the field wires, the current draw went for .3A to .01A. I connected my original alternator and it also draws .01A. Anyone know what inside the replacement alternator would cause this type of current draw. Just curious after spending the weekend troubleshooting...

Sounds like it got a bad diode. It is a very common problem area. Get another one, it should be warrantied.
