78 battery connection
On my 78 about every 2 weeks my car wont start until I tighten the positive side of the battery cable just as tight as I can get it. I've checked the connections and the're clean. Would it help to spray something like WD-40 on the connections?

Use a light coat of vaseline or wheel bearing grease to coat the bolt and the connectors after you clean them to retard further oxidation.

in addition to all of the above, i always carry a 5/15" box wrench, just so i can tighten those side posts. a few years ago, I participated in the 25th anniversary parade of the local corvette club, I am not a member, but the parade was open to all vettes. a lady drove from some 25 miles to be in the parade, and when it time was to line up, her vette was dead. everyone scrambled all over her car for 5-10 minutes, hood up, not really doing a darn thing. I went back to my car , grabbed my wrench, asked the guy to get out of the drivers seat, flipped up the compartment door, 1/4 turn on each post, flipped the key over and her vette fired right up. guy asked me how I knew it was the battery, I said the courtesy light wasn't on when he was sitting in the seat with the door open.
