Looking for Shop/Owner's Manual with Wiring Schematics for 1985 Morbark 12" Chipper

[whfh99]

I am trying to help a friend find a wiring schematic for his 1985 12" Morbark wood chipper. A complete owners and/or service manual would be great but I will settle for just the wiring diagrams if anyone has a copy they can email or post. I am not sure where else to look and it sounds like a few others have had luck here.

Thanks,
