One thing I noticed, and it is not shown in the schematic, is the bottom terminal of the top winding (white wire) is wired to chassis ground in the generator (not in the switch panel.) So neutral on the 120V outlets is shorted to chassis GND.
I hope this is not true and you are looking at a wire for the 12 volt winding or the regulator control winding. Have you made some resistance measurments with an ohm meter to be sure? If it is true, it should be disconnected and allowed to float. Only the green or green/yellow wire should be attached to the chassi. Having the white wire (AKA neutral) on the chassi is a dangerous situation.
Is true. Measured with an ohmmeter as well as saw it visually. For the 120V outlet the GND terminal measures shorted to the neutral terminal. When the generator is on the meter measures 120VAC from Hot to GND (and chassis). I plan to get out there and rewire it when the weather cools off, although the cheesy schematic doesn't show the field cicuitry, only the armature circuit, so I don't yet know if the field circuit relies on the neutral to chassis connection.

Cloudswrest,
You may want to look at this OSHA Fact Sheet Grounding Requirements for Portable Generators If I read it correctly (that's a risky bet :) ), the last paragraph on pg.2 calls for the neutral to be bonded to the generator frame.
I found this link in a reply from "vermilye" in another thread Generator Grounding Thread
I'm interested because I have the PowerWise also.
