Start with testing the generator. Use an inexpensive digital voltmeter to measure the battery voltage. If you find around 11 volts or less, suspect a bad battery. If it is closer to 12.0 volts or higher, remeasure it with the engine running. It must be between 13.75 and 14.75 volts. If it stays around 12 volts or less, we have to diagnose the generator and voltage regulator.
