54MY Lost power on port side 110v upper level

Hi,Does anyone know where the gfci for the upper level (601-circuit) is located for the 54MY 1989? I lost power on the circuit and the fuse is fine, but it see that the wire for 601 is feeding back 3-5V even when disconnected from the AC ships service, so I gather there's a ground fault some where? But I can't find the gfci box...?Anyone?Best regards and happy 4th of July Kristian


Update: found it... First receptacle just beside (left of) the AC ships service switch panel. Problem solved ��
