Just replaced altenator and battery. The battery light is still on and the "check charging system" message keeps appearing. Check for codes on my Gryphon, receiving DTC code P0620 (Generator Control Circ). Cleared it but it keeps coming back??
Any ideas, help or advice???????

Check for loose or broken wire from plug on alt to the PCM on firewall, if no bad wires most likely a bad PCM connection
