It'* not that you can't
... but it would be better if you use the frame itself (kinda like when you jump start). Just about any bolt/screw will do, as long as it is metal and it'* attached to metal.
And as far as the twisty cap connection, could the open end be touching any metal (creating the short)? If at all possible, you should completely seal every electrical connection with electrical tape to prevent any heat buildup or arcing. Treat it like a radiator hose connection... it should be tight enough everywhere to prevent any possible "leaks".
