Wiring diagram
 

Hey everyone! I am new to the forum and new to being a Buick owner. I have only had my 2005 Buick LeSabre Custom for a few months. I LOVE it, but it's making it hard to stay in love with.

I am wondering if anyone knows where Buick (or specifically MY Buick) wiring diagrams can be found? My car is behaving as if it has an alternator or battery issue...we just replaced both due to the alternator overcharging the battery and frying it. However, the newer ones (been working fine for a few weeks) are testing good. We'd like to check the wiring but do not know where to start...
