Testing a power supply
My iMac will not power on, the diag LED’s do not turn on ether. I’d like to test the power supply independently of the logic board. I know how to cross pins on a standard ATX power supply and verify functionary but they have 20 pins and most are color coded. The power supply in the iMac only has 14 pins and there are no voltage or polarity markings I can see. I’ve looked quite a bit online and have been unable to find a pin-out of the EMC 2428 iMac power supply. Can someone please point me in the right direction?
