I always thought the negative posts was grounded to the chassis / frame anyway?

FYI, the red post wire does not feed the generator. The red post feeds the 12 volt battery. There is a difference between ground and negative. Using the frame as negative is OLD SCHOOL. There is one wire to the frame. You have to run a positive wire to the pump so just run a negative with it.
