I agree with Nat.
use a jumper from the F (small) terminal of the gen and bring the wire up to the operating platform. With it running (and charging 2 amps) touch the wire to a bare spot of grounded metal. This will full field the generator causing it to put out max charge rate. It is the same as would be happening in the VR, this is not dangerous.
The amp gauge should show 12 to 15 amps charge.
This indicates that the VR is not adjusted correctly, or poorly grounded to the tractor (Regulator frame to tractor) If it does not produce a larger charge rate, check the belt tension, and fan belt tension. The gen should put out near 7 to 7.1 volts into a fully charged battery. If the battery is not topped up, do that befor testing. JimN
