Park the car with the good battery nose to nose with the one needing a jump, close enough that the jumper cables will reach. (Note: Most vehicles have their eWkkG. 3 Wire Alternator Wiring Diagram. This is a three-wire alternating wiring diagram showing the connections between the different components of a circuit. The circuit comprises three main wires: battery positive cable, voltage sensing wire, and ignition wire. The ignition input wire is attached to the engine. Do NOT connect the black end to the negative terminal on the dead car’s battery! This can risk causing a spark that can ignite the hydrogen gas surrounding the battery. Start the working car’s engine and let it run for about 2-3 minutes. This charges the battery. Then, start up the disabled car. Connect the positive jumper cable to that spot. Next connect the other end of the positive to the positive terminal in the good car. After that connect the negative to the grounding point in Your Ecosport engine bay, and to the negative battery terminal in the good car. After all of that is connected You can attempt to start Your car. Push the 1. Disconnect the (-)negative cable clamp from the dead battery (-)negative terminal OR ground on your car. 2.
