Wiring Tuff Stuff one wire alt.
 

I just bought a new Tuff Stuff one wire 140 amp alt. I am replacing a 3-wire that I converted over. My question is, do I bring power into the same stud on the back that power comes out of? I know I need to go to the batt coming off of the stud but power has to come in somewhere to right?

Yes. One wire from battery to stud...
