Hi, I own a 2001 Chrysler Concorde LXiand recently I began having problems with it. I replaced the stock radio approximately 6 months ago and have no problems, however recently the battery began draining for no apparent reason until it finally died and had to be replaced. I purchased a new battery and had an AVR test done to determine if there was anything drawing power from the battery when the car is not running. The AVR test came back negative so I put the new battery in the car. Everything was fine for a few days, but then I went to start the car and it was dead again. No clicks, no nothing just completely dead. I mentioned the radio because I'm wondering if it is causing the problem. When I installed it, there was a violet wire with a yellow stripe on it and a white plug that terminated the wire. It was originally plugged into the stock radio, but there was no need for it with the new radio. Is it possible that it is somehow drawing power from the battery? At this point, I'm more or less baffled and could really use some professional guidance on this. Any help or suggestions that you could provide to help me with this problem would be greatly appreciated.
All the best
