Not at all if you will look at the attached diagram below.BOTH BATTERYS NEED A CRAP LOAD OF GROUNDS AND EITHER A COMMON BUT EQUIL + JUNCTION POINT or EQUAL POSITIVE BRANCHES OFF POSTS. To say neg off one and pos to starter is a frog leap away from a in series system. Your 2000 posts are impressive, but if they contain incorrect instructons whats the point?

I've ran like this for over 30 years and have never had a problem.
