1965 C337 "Alternator not charging" light

[cessnadriver]

Thanks Dr. Dave. I'll check over the system-as soon as the temperature is a bit higher. My hangar is NOT heated and currently the temp is about 20 with about the same wind speeds. I didn't see the wiring diagram, in the MX manual, showing the "Alternator not charging" light? Do you have it or if not could you draw me the schematic? I checked out your panel VERY NICE! Are all the wires coming from breakers original aircraft wires or are you replacing the wiring as well?
Many thanks, BILLS
