There is a ‘hand-screw’ in the middle of the device that disconnects the battery connection when unscrewed a bit.

2) have installed these on my 1960's & 1970's full sized V-8 automobiles, both with top posts and side posts.

3) I purchased a disconnect unit to install on the 1995 SC-2 Saturn which I recently acquired.
Actually I paid double, about $20, for a Moroso brand to get something first class.

4) Now the size of the Saturn battery seems smaller I an used to.
I tried to screw in the unit. I managed to get both ends started, but I had trouble tightening things down. It just didn’t seem right.

5) Is it possible that the screw sizes are different for the Saturn battery.
Perhaps they are metric, and different from the batteries form the for the 50 year old V-8 cars that I am used to.

6) Do the screws for the Saturn battery terminals somehow have a different thread?
I abandoned my attempt to tighten down the disconnect device and returned it to its original condition.

7) Any suggestions about a battery disconnect device would be appreciated.

All side post batteries are 3/8 NC thread with a 5/16" head. A disconnect is fine for long term storage but just using a good maintainer has advantages over just leaving a battery set. Computer controlled cars do not take well to being powered down for long periods and then repowered multiple times.

REWARD EXCELLENCE!
