Hello everyone. I am new member to this forum as I don't own a Cadi but my brother is the owner of a 2002 Cadillac Deville that he purchased a few months ago. There was a new battery installed in the car but that battery is pretty much toast now due to a parasitic draw issue the car is having. I am posting here to see if anyone can help me understand the issue a little bit better as I told him I would try to help him out.
Knowing all the electronic features of these things, I am sure any small unordianary draw on the battery will cause the vehichle not to start. I am going to call the PRND321 (the gear display) is always on. Even if you take the key out of the ignition, that display remains on. I can only assume that something tied with this is the cause for the draw on the battery.
I searched and searched and could not find anything on this issue but a point in the right direction would be great. Remember, I have no idea how the system works. What I did find is that it could be the ignition system, like a switch or something?
Thanks for your help
