Could be;

• Wiring from/to Generator faulty
• Voltage Regulator faulty
• Generator faulty

In which case;

• Check Wiring from/to Generator
• Check Voltage Regulator
• Check Generator

Usually the thin (0.5mm CSA) blue wire from the alternator to the j519 Onboard supply control unit ECU breaks inside the harness, somewhere under the battery where it goes from the body to the 2 pin gearbox plug near the starter.
