Loose + battery terminal
Hi folks, my dads ZR-1 seems to have some ongoing issues with the positive battery cable bolt. Even when it is decently tight it seems like there is a crap connection to the battery. I also noticed the negative cable has a much larger bolt going into the battery.....why not the postive also? Any way to upgrade it?
It just seems that the little 5/8" bolt barely makes contact. Any and all suggestions appreciated. |

Re: Loose + battery terminal
I thought the cable connection bolt to the battery was like 5/16 (small size near this) and they were both the same. The last time I had an experience with two different size battery cable bolts like this, someone had drilled out the one cable to fit a larger bolt thru the cable.

Re: Loose + battery terminal
on my 90 the positive and negative attachment bolts are both 5/16" heads.
I think there is a bit of fussing to connect both terminals as they have ridges that inter-lock like gear teeth. If you don't get them to mesh, then the bolt can't hold the cable end to the terminal securely. JMHO.

The threads in the battery are blind tapped and shallow. Sounds like the bolt you are using is a tad too long. If so, it will bottom out in the battery threads, leaving the cable "loose". Jerry

Re: Loose + battery terminal
[IMG][/IMG]Whatever you do dont crank down too much on the battery bolt,you could end up with this.Funny how the guy that I paid to inspect the car failed to notice this,or the guy that sold it too me didnt mention it either.The battery lug will break off the battery and acid will go everywhere.It was so extensive on my car that it ran down into the rocker panel and out the back.Heres a shot AFTER I fixed it.[IMG][/IMG]
