How to Hook Up a Battery Back to an Astron Power Supply
- 1). Cut the trace on the PCB of the Astron power supply. Cut it between Pin 4 of IC UA723 and the R5 wiper.
- 2). Use a 10K ohm ¼ or ½ watt resister to bridge the cut you just made in the trace.
- 3). Set the output voltage by adjusting the R5 wiper to the desired voltage amount.
- 4). Hook the battery to the power supply by clipping the black clip to the negative (-) symbol and the red clip to the positive (+) symbol.
