12.8 WITH Engine running? You are NOT getting Alternator power to the RV. Most (99 percent) of motorhomes the chassis alternator is part of the chassis harness and not part of the Motorhome Coach battery charging system. That means that the Alternator will charge and show voltage to the chassis system IF the Alternator is operating. From your description, the problem is at the Alternator. The Dash indicator is doing its job. Faulty Alternator system. Doug
