I have a Pathfinder series plotter and radome.  The radar is not transmitting.  The radome is moving, but the plotter says "scanner not responding". I performed a resistance test between pins 6 & 10 on the cable from the back of the Pathfinder Plotter to the radome.  I got 170 ohms, confirming the cable and scanner integrity.  I then tested the pins on the plotter, 6 & 10, and it was an open circuit. Does this mean that the plotter unit is bad?  Is this repairable?  Cost and turn-around time?Is there something else to test?See More
