1. You don't say how much it discharges on meter. You could polarize generator by momentarily jumpering from generator armature post to BAT terminal (wire to ammeter) on regulator. Touch the nut and not the threads on the armature so when it arcs it doesn't damage the threads. Polarize with tractor not running then see what it does when you start it up.
2. Ground field post on generator (tractor running). If it now charges you have a regulator or wiring problem.
