PO63C "low generator voltage" Check guages light and beep

Had generator bench tested and was perfect. I was getting 14.8 volts at battery before .Cleaned all posts and connectors ,reassembled and have 14.7 at batteries and ECM post.
Clearing the code with Race Me tuner and when it self diagnoses , Im still getting this. Curious if anyone has encountered this . Its a 2008 Dodge Cummins cab & chassis.#@$%!

I got it all the time with my 2010. The dealer replaced PCM, Alternator and several wires. After they couldn't fix it, they blamed by aftermarket lights. I removed the lights and it still did it. Traded it off and the new owner is still fighting the problem. (Aftermarket lights were wired into the upfitter switches and not cobbled together)
