I believe I was quite careful to follow the instructions with the single point ground, soldering the connections. The ground from the R/R was about 16 inches long and ran to the starter solenoid bracket. I shortened it to about 4-5 inches and ran it to the single point ground which is on the right side of the R/R. The other SPG wires run to the battery, frame at the front of the battery box and the starter solenoid bracket.
The "key on" number must be telling something but I don't know what. (Edit: I guess that means a weak battery. It's only a year old. Any other way to test it? It is not the one that was in the bike when the charging system failed--that one is on the charger...Um, the water in the battery is low also.)
The "5000 rpm" number is pointing to a connection issue if I'm reading the directions correctly but I am confident about the SPG and I couldn't find anything on the positive side that looked suspicious but I don't really know where to look beyond the battery and panel area. (No corrosion on the fuse box--applied dielectric grease).

The two wires I repaired have the transparent pink connectors:
