Does the GEN light come on with key ON before starting the engine?
Does the GEN light go out with key ON and engine running? With engine running, measure all 3 wires from the alternator to the relay board with respect to chassis. Please report what you measure. Also measure the battery voltage too. |

13.4 V at battery while charging (IIRC). Your voltage regulator is probably shot.

First things first - put your battery on a charger and charge it back up. I'm amazed a battery with 10 volts will even start the car.
