I have a C66 where the internal meter is disconnected. I would like to reconnect it and need to know how the green/white/yellow were connected to the ABC springlocked-points at the LP1 Main board. Also there is a modification where the mains and 12 V inlet/outlet are located. Seems the switching triac or such (mounted to the metal plate) was taken out of the loop. Has anybody got a picture or schematic of these.? Thanks!
