    keyword=LQ2 work done - Late Entry

    This is the work Jessie and I did on the LQ2 yesterday. There is a disconnect somewhere from the A0 output flag, with the cables with the red tape on the ends, to the screw terminal in the "black handled" switch. I could not locate it exactly, but I suspect the local/remote selector at the rear of the power supply. I ended up running a pair of wires directly from the output flags to the screw terminals in the "black handled" switch. The output voltage is now displayed on the local display module and fed into the regulation module, as it should be. The inability to remotely set the current was due to a bad pin in the backplane connector for the local display module. The pin could be pushed back out of the connector, thus no contact to the pin of the local display module. I pushed the pin completely out of the backplane connector. I clipped one end of a minigrabber to the free pin and the other end of the minigrabber to the contact of the remote/local switch of the display module. The power supply operates in all respects as it normally should. These two wiring problems will take a few days in January to repair in a more permanent fashion.
