Jocko_51_B3B Posted April 26, 2020 Report Share Posted April 26, 2020 Since I'm working on my B3B's wiring right now, an interesting question popped into my head. Let's say my battery is a little low but is charged up enough to start the engine. I start the engine and turn ON the headlights and all the accessories. Everything is working fine. The ammeter shows the battery charging normally. Here's the question: With the generator providing current to all these things, how is current returning to the generator? Does return current come up from the frame through the engine block and generator mounting bracket into the generator? Or should there be a ground wire running from somewhere on the generator to the frame? If the generator needs a ground wire, where should it be connected and what gauge wire would be adequate? I just know that whatever current the generator puts out has to come back to it and right now I can't see a reliable return path. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted April 26, 2020 Report Share Posted April 26, 2020 the theory is any energy not being consumed is being stored....chassis and one side of the battery (you chose polarity) is common... Quote Link to comment Share on other sites More sharing options...
Tooljunkie Posted April 27, 2020 Report Share Posted April 27, 2020 (edited) Generator Housing,chassis and body all serve as the return path. under most driving conditions the generator provides enough energy to operate all the accessories And then some to maintain charge in the battery.
