Troubleshooting alternator and 2010 Buick enclave

Troubleshooting alternator 2010 Buick Enclave. You’ll see how I spent a lot of money because I chose the wrong replacement alternator for my car. This video does not do a very good job going over the actual replacement of the alternator. I would highly recommend other videos for that. However I do go over some troubleshooting steps that could be useful.
