Re: Dell E171FP No power
I'm not sure where the problem is occurring. Obviously, the 'power switch' is getting less voltage with the logic card attached. Looking at the application note for it, the recommended Vcc is 24 volts. That MAY be a false clue.
First, is there any label, printing, etc. on the board indicating it's output voltage and current rating? Second, if the 5V output is rated at more than 2.5 Amps, buy Radio Shack Catalog #: 271-131. This is a package of two 1 ohm resistors. Connect them in series from the 5 volt output to Gnd. Then with the logic card disconnected, plug the power supply in and measure the output voltages.
