This makes me think you have a grounded generator light circuit.
if this circuit gets grounded, the generator will simply dump all of it's output into the ground. The result will be a discharged battery.
To check this, do the following. I have marked what I suggest you do:

With this set up, if there is a ground somewhere either in the wiring or a short at the base of the bulb, the light will stay on. This dumps the generator charge to ground.
Your machine is a 1981. If your manual shows the signal light with a wire going to ground, then that is different from what I am accustomed to seeing.
So, what does your manual tell you to do with regards to 'Checking the Generator Signal Light?'

There should be diode between regulator and generator light, in all systems that have electronic regulator. -77 new bikes came with electronic regulators. Check that diode is ok. It can work without that but...
