Usually it's the other way around, no light and as a result, no charging either!

That light is in the voltage path to the regulator that in essence, "turns on the voltage regulator" which in turn excites the alternator and lets it start charging. No light, no excitement, no charge.

,,,strange that it is staying on, I wonder if that is indicative of the voltage regulator being bad, in that the voltage remains high in that circuit? I hope someone weighs in on this problem with what to look for.

Meanwhile, I'd double check all the voltage regulator wiring connections to make sure each one is making a good contact. Look inside the plastic plugin connector and see if any of the wires are pushed back in to far and not making contact where it plugs in.

I am of course assuming your alternator is charging normally, as you seemed to indicate that is the case. I'd also run a voltage test at the battery to make sure it's not over charging because of the possibility of the voltage regulator being bad. Voltage should not exceed 14.5 volts at a fast idle rpm if the regulator is working properly.
