After work today I stopped to get gas with my 2002 Mercury Sable with the 12v Vulcan motor and when I tried to start it all I got was a click instead of turning over. This has happened a few times before in the last two weeks but it usually ended up turning over about a minute or two after, so I figured it was just a battery cable or something and I’d fix it eventually. But now it refused to start so i decided to try and get a jump from someone to see if that fixed it which it didn’t. Next I tried beating the starter which also didn’t fix it but I also don’t know if I was hitting it with a hammer in the right place, but soon after that I tried to start it and randomly it just started about an hour later and i drove it home, then I turned it off and it started right back up, but then I tried it again and now it won’t start for any reason. All I get is a click but sometimes it will try and turn over but fail, almost like it loses power right before it fully turns over. The battery is brand new as of a month ago and the alternator was changed about 2 months ago. Does anyone know what the problem possibly could be? I’m thinking it could be the starter but I’m not sure. I uploaded a video of what it sounds like youtu.be/exHxRJ1hr04
