Sounds typical of a bad diode in the generator. That will reduce its maximum output to one third of its rated capacity. With a common 90 amp unit, 30 amps is all it will be able to produce which is barely enough to run the fuel pump, ignition system, injectors, and a few lights with nothing left over to recharge the battery. Have a load test performed with a professional tester that also measures ripple voltage. With a bad diode that ripple will be very high.
