boomn89 Posted November 7, 2008 Report Share Posted November 7, 2008 OK I am getting ready to install a EA 275 amp externally regulated alt on my car, it will only be charging the back 8-16v batteries. The factory will also still be on to run the rest of the car. How many runs of wire do I really need to charge the rear batteries? Would one power and one ground be fine?
