Hi, on the 20pin Molex connector you have Pin 14 has an internal pull-up to +5V. When pin 14 is grounded the power unit will come into full operation, all you need to do is S/C pins 14 and 15 to switch it on. Then just get a fluke or an avo or similar and check all the voltages. You must know what the voltages on the various leads are?? BTW you will know when the P/S has switched on because the fan will start............ |
