Well, that's good. Speaking of grounds, there's one on ERA cars that, unless someone told you where it was, you'd never find it. It's on the front, driver's side of the X-member. It's not on the engine side of that round piece, so it's kind of hard to see. A lot of the electrical components (fans, horns, head lights) get their ground feed from that connection, so it pays to check that. The other ground source is to the firewall right behind the passenger side cylinder head. That one's easy to see. The rear ground feed is easy to see, too. It's in the trunk, driver's side, where the quickjack/bumper bracket is bolted down. It wouldn't hurt to just find them and snug them all up.
