I have replaced ignitor, Battery, belt and checked the system over. Cannot get the belt light to reset. When resetting light the light will flash quickly for 2 sec and then turn slow without disconnecting the 2 pin connector. Only getting a reading of .5 volt on the brown wire and no voltage on the blue and white on with the connection not connected. also tried swithing the engine brake acutaor with the 4 wheel drive one seeing they are the same acutaors. Still no change in voltage or system problems. Any idea's?
