The schematic locates the capacitors in the rotor for\nelevation and in the control box for azimuth.\n\nThis unit uses relays to perform the actual switching. So check the following:\n1. Disconnect wires 4, 5, and 6 to the elevation rotor. If you don't disconnect the wires, you will get a reading on both pins 4 and 5 measured from pin 6 due to the run capacitor.\n2. Use a voltmeter to check for AC voltage between pin 6 and Pin 5 when you press the UP button.\n3. Check for AC voltage between pin 6 and pin 4 when you press the down button.\n4. I don't know the exact voltage but would guess something around 25 to 30 volts AC.\n5. If these work correctly, the problem could be the limit switch, the run capacitor, or the motor, all located in the rotor housing.\n6. If either voltage is not present the problem is in the control box and could be either the relay or the relay driver transistor.\nThat should help pin things down quickly. I'll send the schematic directly.\n\nJohn Kopala\nN7JK\n\nHi Folks,\nhope in an help to solve my problem with my Rotator Yaesu G-5400B.\nToday i was tracking the ISS, ad while i was tracking it I got The AO-51 in\nAOS. As I am using the Trackbox, and i did not have under my eyes the\ncontrol box, I heard the Trackbox passing from ISS to AO-51. I gave an eye\nto the control box and saw it was stuck at 35 degrees and it did not go\ndown to the 0 degrees to start the AOS. I have pulled out the connector\nwhich connects the control box to the Track box and tried manually To bring\ndown the antennas. I've tried to press the \"DOWN\" switch, but they did not\nmove from that position.\nI've tried to press the \"UP\" switch and noticed that the antennas moves\ngoing up.\nThen i have tried also with the \"RIGHT\" and \"LEFT\" switches of the Azimuth\nand noticed also that the antennas moves in both sides.\nAt the end i can say that the antenna moves in all the positions except for\ndown.\nPlease anybody can tell me what is happened?\nAs the antennas are now stuck at 45 degrees i am afraid that the wind can\ncause problems.\nI Hope in an help.\nAny help will be really appreciated.\nThanks in Advance\n\n\n73 de Enzo IK8OZV\n\n", "attachments": [] }
