If the blue field was shorted to ground you'd have a smoking wire, if the green field was shorted to ground you'd have maximum voltage output.
That's right as my buddies 71 Roadrunner had the alt rotor short to ground right after the brush fed by the blue 12 volt ign voltage and burnt his fuseable link out and started to melt some wires. I had to replace the alt and fuseable link and repair some wires on it. Ron
