More Electrical Help ...

The jumper was from A-1 to S-5 the key was off. Also, when I looked at your drawing, I noticed the A-1 and R-6A wires appeared to be reversed (from the drawing, it was hard for me to tell which goes to what pole on the ammeter) so I reversed them to look like your drawing...
My drawing is just based on what we see in the shop manual. At the same time keeping it simple to read as a schematic.
Go with what with what the factory did!!! We can change the drawing to match what you see.
The A1 (battery) should go the terminal that leads inside to the ammeter.
The R6 Alternator output should go inside direct to the main splice.
