I had an unusual (for me) experience this evening. While starting the green sled, the headlamp and instrument lights came on as normal but then they all simultaneously dimmed to about half of what they should have been. I have not seen that before, has anyone seen anything similar to this? Sled seemed to be running fine otherwise. We are out of snow, so I didn't drive it anywhere, but I expect that the light output of the headlamp would have been insufficient to see by.
I will add that the intensity of the light did not increase with increased throttle. I will have to find some time to check voltage.
