Hi!
I know the subject has been brought up before, but the topics I have read has not made be any wiser than before, so here goes!
I have a full tower AT 486 computer with the red rocker switch.
I have replaced the AT power supply with a new old stock AT power supply, AE, model SPA-4250
I have the wiring diagram and the cables are white, blue, black and brown. The green yellowed cable is for the ground.
I tried to wire it just like the old power supply and used it as a reference. I have read that you can really mess up if you are doing it the wrong way.
Initially, I put the white cable on the upper left on the rocker switch as (1) seen in the picture, the black to the lower left, blue cable right next to the white cable and the brown at the lower right.
Fired it up and no response, the light in the room went out and I needed to switch the circuitbreaker on again.
The power supply works with the push button switch it came provided with and it worked when I got back to that push button switch.
Can someone help me out, what have I missed?
Either I have mixed the wiring or the switch itself isn't compatible.
