With all due respect, if you're running at night and your battery stays up, the generators charging...
If you're comfortable taking the generator apart, look inside the case, towards the back (where the armature windings are soldered to the commutator): if you see a thin silvery line around the inside of the case, it's "slinging solder"(the armature windings overheating the solder connection to the commutator) and about to quit charging.
If none, and mica is OK (if mica high it's at least an armature rework or replace)commutator may just be dirty and/or brushes contact area glazed or corroded from sparking/arcing; my Delco book sez to use 00 sandpaper (NOT emery cloth) until commutator clean/shiny. LIGHTLY clean brush contact surfaces, keeping curved contact surface until looks clean.Commutator can be cleaned with gen on and running (if you have the removable cover-band type) but taking apart easier because it lets you check and clean the brush holders and springs for easy movement and good tension. If you have cover-band type, and no cover band, get one; it keeps dust etc out. Good luck.
