Verify Generator Is Source Of Radio Interference

Start and run the engine. Tune the radio to a station where the interference is present. Turn ignition off. Disconnect generator single wire connector (Black/Orange wire). Start engine. With the engine running, is the interference present with the generator disconnected? If yes, diagnose the in-vehicle entertainment system. If no, install a new generator. See GENERATOR under REMOVAL & INSTALLATION. Test the system for normal operation.
