Hi joshua fenwick. Welcome to the forum. Start by using an inexpensive digital voltmeter to measure battery voltage. You should find near 12.6 volts when the battery is fully charged, and you must have between 13.75 and 14.75 volts when the engine is running. Also measure the voltage on the large wire bolted to the back of the generator.
