at the parts store they sell a wire mesh, you put it over the threads and screw it in.

you can try the good old tin foil trick too. take some tin foild, fold it up a few layers thick cut to a inch wide strip, then wrap the treads and only snug the bolt, it wont take a full on ape-ing.

or if the bolt threads look worn out, you can try changing the bolts in the cables.




last ditch effort would be a new battery.
