Just about every one new or old I have ever seen

 

My guess is that manufacturers save some money (ten cents x XXXXXX vehicles) by not having to put a cover on the negative post.

If a tool or piece of metal dropped onto the negative post, no circuit would be completed (as would occur with an uncovered positive post), so a cover is less necessary.

I think some of the newer cars come with covers over the negative battery post as well, and aftermarket covers can be purchased (got one for our MR2 Spyder).

 

probably for testing too...that's a sure fire ground to use for the other end of a test light.

 

Because it's voyeuristic

 

Agree with all the above, except thoiboi of course














because the word he’s looking for is exhibitionist

 

Engrish isn't my first language.





Also I wish I had mod privileges and just changed that and made you look crazy

 

Sounds to me like OP is also looking at other people's negative battery posts so technically, @thoiboi got it right the first time.
