Just finished mine thanks to you guys. Iíve had this supply for a while but just couldnít get it to start. Reread all the posts, comparing to the other Dells, and about 15mins of trying different combinations on the control pins then BINGO, heard a relay click then the fans started. (He smiles).
I found three trim pots on a circuit board in the power supply which I hoped adjusted the voltage. I marked the wiper positions with a fine marker so I could always find the original settings in case something went wrong. One trim pot did indeed adjust the voltage. I donít know what the other trim pots do. Range was 12.6v to 13.6v.
No problem with over voltage shutdown at 13.6v.
Iíll only be using this supply at about 20A for now hence the use of only one pair of output blades.
The pictures below explain the connections.
Great thread, thanks guys.
