Check the dimmer switch.

I am confusing myself here . All 3 dimmer switch terminals have power to them at the same time . I thought that they should only have power to two at a time . Does that condition point toward anything ? All 3 terminals also had power with the dimmer switch removed . I did try a new dimmer switch i have as well . same result .

I did try to pull a headlight , but one of the screws for the bezel is stripped . i will get creative with that soon .
