Abstract
Abstract In an emergency vehicle having dual batteries, one of which is employed for supplying power to the electrical system of the vehicle chassis and the other of which is employed for supplying power to the emergency equipment, dual alternators driven by the engine are provided for charging the batteries. The output of each alternator is connected to the input of its regulator and to both batteries whereby both alternators will be on at all times when the engine is running and will share the load on either or both batteries.
