Thanks for posting.
It's not necessary to remove the alternator to test it, the best way is to test it in the car withan charging system tester, as far as I know autozone just uses a little hand held device that does not test the charging system under actual load conditions. the door open sensor will not draw enough current to cause this so please have someone test the charging system tested using computer controlled charging system analyzer.
Thanks for the reply I understand what was already done but I would like to confirm the charging system output using the method I have described, this was four years ago, so I would verify the charging system condition at this time. four or five batteries in that time frame is not normal so I'm wondering if these alternators are charging the batteries back up, the charging light is on for a reason.
