Battery Cable - Negative/ground
What is "it"?
The end of the new cable with the small pigtail wire normally bolts to the battery post...but in your case it can be bolted to the frame if necessary
Usually the threaded hole in the battery post is about three threads deep (designed to be stripped out!).
If you convert to a 3/8"-16 TPI bolt you need some flat washers and a lock washer to "shorten" the length of the bolt you have now in order to prevent stripping the battery post threads.
(We have alot of info going back and forth...maybe you can pick one problem and fix it...then move to the next problem)
