Check the VDC at the battery, static [not running] should be 12.5vdc.
At 3000rpm, it should be appx. 14vdc.
Anything less that that, and you might want to look at a new regulator. It is a dual output unit and one line feeds the lights and the other feeds to the battery. It can pop the diode on one side and still function on the other.
