@el polo ...that's exactly what I was showing. I ungrounded the back side of the lighting coil. The picture was showing that on a hpi mini. What u then do with the DC side of the equation is not at the stator it is at the black wire of the five wire trailtech. And yes the DC is not frame grounded.
And if u simply want to run , for instance , a halogen on AC ; two wire ac via a trailtech two wire ( the base of the two wire is grounded to suck up excess energy) , the halogen will in my experience look better.
