Possibilities include:
Overload, such as additional lighting exceeding amperage rating of the stator
Dead short on stator wiring

Stuart, are you stating that it's not possible to overload a generator, AC or DC and thus overheat windings as well as sag voltage?
Perhaps this link will better explain possible winding failures, as motor winding failures are generally in common with alternator winding failures.

In post 6, the possibility of an overload or dead short was dismissed.
The Electrical Apparatus Service Association link included photos of failures:
1. turn to turn
2. shorted coil
3. winding grounded
4. overload
EASA was formed for motor rewind shops to share motor winding and lead connection info and there was no internet when I served on the board of the SoCal chapter in 1980-1981, so I thought it helpful to now be able to share photos.
When I managed an industrial electric motor rewind shop, circa 1979-1983, we were a warranty station for A.O. Smith, Baldor, GE and Toshiba. Coil damage proved or disproved a warranty claim.
If you prefer that I not post in this forum, I will avoid doing so in the future. No point in an Irishman and a Scot arguing.
