If it has a ODB switch, the use ov a voltage regulator is necessary. The F terminal on the gen should attach directly to the Field terminal on the VR. If it is not that way, I believe it is then either grounded (making it charge as much as it can) or if the field is grounded internally from a short to ground in the gen, it could also stay at full charge output.
First take the field terminal loose at the generator. (the wire will not be a "hot wire" so it is not to be worried about. If it now does not charge, we are getting better.
Next use a different wire to connect to the Field terminal of the VR. (with nothing else connected there). If it now charges, but not as much, or charges less after a few minutes, it may be fixed.
Use a reliable (good) digital or analog meter to check charging voltage, it should be 7.2 to 7.5 volts with a charged battery. Any more than this and it will over charge it.
I hope this helps, John Ts charging system diagnosis chart is also standard best practice. JimN
