Quoted from 1stpingalaxy:Can anybody point to what points/wires/colors are what voltage pairs off the transformer?
The Galaxy transformer/rectifier board schematic is below (click to zoom in).
The transformer lugs are numbered - it might be a bit difficult for you to see some of the numbers since mice ate some of the transformer covering.
Anyway for the G.I. power wiring:
Transformer lug 17 has a blue wire that goes to the rectifier board and as is soldered at point E7
Transformer lug 18 has a black wire that goes to the rectifier board and as is soldered at point E8
You should measure 7.3VAC between lugs 17 and 18 at the transformer and also across points E7 and E8 on the rectifier board.
