Hi, my name is***** will be assisting you.

You are correct in that the video is not correct for your engine.

Your specific engine does not have a voltage regulator on it according to the information that is provided by Kohler utilizing your model and spec number from the engine.

The alternator or magnets in the flywheel may be bad causing your problem.

You stated that you are getting 28 VAC from the white wire and only 3.9 VDC from the red wire which tells me that the DC side of the alternator is not functioning properly or has become shorted out. If the magnets in the flywheel were bad then the AC volts on the white wire would also be affected and based on your information that doesn't seem to be and issue.

I am including a diagram of the electrical system on your engine. You will notice that it does not include a voltage regulator in the system.

I will be glad to answer any other question(s) that you may have.

Thank you it has been a pleasure to assist you.
