Apple II clone power supply repair

I have replaced some of the capacitors on a power supply that I have that has come out of an Apple II clone (MICRO II) but I want to test it before I reconnect it to the board. The problem is that the +12v was actually putting out (if I remember correctly) over 15 volts. All of the other power leads are in range. I understand that the power supply will not stay powered up unless it is connected to the board or is fooled. What I need is for someone to explain to me what resistors do I need and how to wire those resistors up to fool the power supply so that I can take readings. Thanks
