HHR not starting, lights flickering, check your grounds.

Most cars today run on ground switching to run properly. Just a tip on cleaning the paint off where the cable has contact for better contact.

Thank You! This fixed my new alternator overcharging the battery issue! 15.2v down to a nominal 14.45v.

This was enlightening and helpful too. Got a new battery too because the Installed
one was four years old. Makes me wonder about OTHER poor ground connects too.
Thank you! Peace

Also I used my Dremel tool to scrape off the needless paint, and conductive grease.
