I agree with iowagold, flash the field as a 1st step: With engine running apply a suitable DC voltage across the field windings.
A small 12 v battery is fine, just observe and keep the correct polarity. A momentary voltage application should result in output ac voltage.
Once the field has been regenerated it should thereafter be self-sustaining.
However, there are certain conditions that could interfere with the residual magnetism necessary for field build-up. But try the field flash technique first, see what happens.
