Are we saying that when 12vDC source is needed we should not use a ground from the frame?
i.e. I want 12vDC for a macerator pump in my wet bay. Because of proximity and ease of wiring, is it safe to connect the 12vDC positive wire to the red post that feeds the generator, and connect the 12vDC negative ground wire to the metal frame of the generator?
I always thought the negative posts was grounded to the chassis / frame anyway?
