Charge the battery for a few hours on a low amperage setting, then start the vehicle. Immediately put a voltmeter on the battery and record the voltage. If the voltage is below 12 volts, then you have a charging system issue. I would check fuses first, then the alternator power cable. You check this cable by doing a voltage drop test. Set your voltmeter to volts and put one lead on the positive terminal (battery) and the other on the power cable on the alternator. Start the vehicle, you'll get a low voltage reading, most likely around 0.1-0.5V. If you see anything above 0.4-0.5volts, replace the alternator cable. If the reading is low. Replace the alternator.
