According to Bitmain (link below) you should get

12 ± 0.5 V, it means that the PSU is working fine. If it shows 0 V, it means the PSU is not working and needs to be repaired.

the link also includes a guide on how to test your PSU without having to connect the miner.

you can search youtube on how to change the PSU fan, also you should post a link for the fan you bought, it could be the wrong fan after all.

Yes on the yellow wire. I contacted the seller and they said the yellow wire was for testing RPM. Any idea how many volts I should see coming out of just the APW 3+ without the miner connected? Unless I'm testing it wrong, I have no voltage across any terminals. This is weird because the APW was working when I shut it off. I changed the fan (pretty simple to replace) and now nothing seems to work.

The fan died in one of my APW 3+ power supply's. I bought a new fan on Amazon and it was delivered today. The old fan was 2 wires (one black and one red). The new fan (same model number) had 3 wires (1-red, 1-black, and 1-yellow). Thinking the yellow wire was just an auxiliary ground I connected the black and red wires and left the yellow hanging. Powered up the power supply with the S9 connected and nothing. Fan on the power supply not turning, and of course the S9 not working. Both the S9 and the power supply fan were working prior to taking it off-line. The old fan was about to explode so I shut it down until I could get a new fan.

Does anyone have any experience with this? If the fan power supply is not working will that keep the miner from mining? There is 220 going to the power supply, but not sure how to test the power going to the S9. Did I buy (or did they send me) the wrong power supply fan ? Any help would be greatly appreciated.

Take a look at position of the wires, most likely the third wire is only to report rpm, but the colors might be wrong... Assuming you bought the same voltage.

Unless the miner is damaged, you could plug only the controller to see if its delivering power (or use a tester). Under a low load (just controller) it should work. Under normal load (with hash boards) without fan it would overheat.
