I recently replaced a bad starter on my 07 G6 3.5L. It starts up fine but now it seems as though the alternator is not charging the battery. It's a brand new battery but after a few minutes the battery light comes on and when I put a meter on the battery, it reads around 11 volts. The fuse and relay seem to be fine. I'm not great with automotive wiring but could it be the fusible link wire?
