Looking at the schematic, with a meter you should have 12V on both sides of the fuse. Then from there, the same holds true with the black wire on the key switch. Using the legend in the schematic, you can find where 12V is supposed to go based on the position of the key switch. I have included them for reference. Hopefully they will be readable. If not, I can email them to you if needed.
