Hello I receive a AP WRV54G, to test and fix some problems. But, the Ap donÂ´t have the original power supply. I need the original power supply details ( Voltage, Amp, polarity ) to make a new AC Adaptor to use on this AP. The voltage and Amp, I know ! ItÂ´s show on Manual. - 5V 2,5Am. But the polarity, I donÂ´t Know. I need the Polarity about Central Pin and the external on AC Adaptor connector. Please, If someone have This AP, look at the details on AC Adaptor and post here ! Thanks.
