I have an american autowire harness for my truck. There is a wire that goes from the harness to the bat stud on the starter, and a wire that goes from the bat stud on the starter to the bat stud on the alternator.
This is probably a stupid question, but it doesn't say anything about it in the directions. Do I need to take a good heavy guage wire and run it from the battery to the starter also?
Does a wire need to go from the alternator bat stud to the battery also?
Can I ground the alternator to the engine, and the engine to the frame, and also the battery to the frame?
