AH OK then I'd say VR drop is good. Next, make sure the green brush connection is not grounded. Remove both field wires, check one or other brush/ field to ground for resistance, they should be OPEN / infinity. If they are, make sure VR is grounded, and if so, replace VRThat was from battery positive to those two locations. And I made a mistake. The readings were 0.20 and 0.26.
