Johnson Iron Horse Generator

Evening, all.
Just got this little Johnson Iron Horse 12v generator today. Have been eyeing it for a long while, being an 1800rpm unit it would be nice for running an inverter at shows.
Anyway, just got it inside tonight, checked out the control box, and tried turning it over with the generator/starter.
When power is applied, and the starter is pressed, the engine promptly binds up tight, and the ammeter pins to the -.
After pulling the side cover, I found one of the field windings completely loose.
I have about zero experience with generators like this. anyone around here have one similar?
Nervous to break it even worse, been wanting a low speed generator of any sort for a while now.
