on the 2 field circuit system you pretty much just need switched 12V via the blue wire circuit to (1) the the top terminal in the VR triangle connector with the "top" being with the triangle being "up" like a pyramid and (2) T ing off of it to either one of the male alt field terminal (blue wire). Then the green wire runs from the "side" VR terminal to the other alt male field terminal. Is that what you currently have wired? That's all you need for the field circuit to make it charge
