Thanks for the answer on the Goodman SSZ140241AF.

Not sure if DC board is wired correctly on above referenced unit. Need link to DC PBCDM130 rev B wiring diagram. Current wiring at unit has black wire from dc port O (5th from rt to lt) going to RVC and rtn to main contactor on common side which ends up back at dc port C(blue wire).

Diagram I have shows 5th port as why not O. No reference to model number of DC board.
