2007 Trailblazer SS
Replaced the alternator a few weeks ago, with a new battery didnt think anything of it! Randomly wouldn't start one night so i tried to jump it but was on the side of the road and couldn't get it started via jump so i had it towed under my insurance to my local repair shop. Said the new alternator is charging the battery too much, and causing issues. They proceeded to charge the battery back to "normal" and now it starts just fine. Got the alternator on rockauto so its under warranty, but thought i would post to see if anyone else had any other ideas beside just replacing the alternator under warranty . Should i try something else along with the alternator replacement?
