How do I adjust Voltage Regulator on Hyundai HHD 1250 Generator

SOURCE: 1970 VW Beetle voltage regulator

loud your battery again and see if ti keep running it down--if yes check the battery loading size it suppose to be around 12-13.
less then 9-10 in most cases it's the alternator cause another thing is your battery could be out of work

As far as I can tell on the wiring diagram for this generator there is no voltage regulator unless it's incorporated with the auto throttle unit.
To lower the voltage you need to lower the speed of the generator engine. To do this there should be a screw on top of the engine under the tank when your facing the recoil. This screw presses on a arm that controls your governor. Turning it in (righty tighty) will increase rpms, turning it out will lower them. You should see the voltage change on the voltmeter.

Cummins P2200, 2KWatt, it starts fine, but after a couple of minutes, it gives quite high voltage output, meter needle goes beyond 300v, engine speed seems high since throttle is increased, indicator light on generator also becomes bright, after a minute or so, things come to normal, sometimes takes few minutes to come to normal, situation is same, with/without output load. this happens within initial 15 minutes after startup, afterward everything is normal.

SOURCE: which post is which on generator on a 1975 sportster?

the post should be the same as an original. The wires should be green and tan. Green wire goes to the post towards the front wheel and the tan to the post nearest the engine. Don't forget to "polarize" the generator before starting. procedure is in the service manual. Momentarily short between the battery positive post and the field terminal.
