fox Posted July 10, 2023 Report Share Posted July 10, 2023 Anyone know what resistor R6 is? I tried googling it. The one in my psu is cooked a little and the color bands aren't readable, it came that way. It has not been a problem but I think I'll get a replacement while I'm buying other things just cuz.

Bowlsnapper Posted July 13, 2023 Report Share Posted July 13, 2023 Find a good PSU and use this method to test the resistance. Pick out a random resistor and set the multimeter to the 20kΩ setting. Then hold the probes against the resistor legs with the same amount of pressure you when pressing a key on a keyboard. The meter will read one of three things, 0.00, 1, or the actual resistor value.

fox Posted July 13, 2023 Author Report Share Posted July 13, 2023 I know about testing resistance, but I have an analog meter, it won't show me a precise number. This resistor's value may have drifted, too. Quote Link to comment Share on other sites More sharing options...
Bowlsnapper Posted July 14, 2023 Report Share Posted July 14, 2023 Maybe go digital? I'm not an expert at ALL though... I think @SS_Dave has some experience with analog meters... Quote Link to comment Share on other sites More sharing options...
fox Posted March 9 Author Report Share Posted March 9 I recently bought another of this PSU and found that, for some reason, R14 is a different value on each of my two units. It's 1 ohm on my current PSU, and 3.3 on the new one (going by the color bands). This is odd. I assumed xbox PSUs to be identical according to model+revision and have never read anywhere that two of the same PSU may actually vary in component values here or there. It makes me wonder how and if the rest of the circuit is different. Is it even safe to transplant mosfets, diodes etc from this new PSU if my current one goes on the fritz. Oh, and R6 is a cooked mess on the new unit, too. Lol. Ended up with only more questions and no answers. Quote Link to comment Share on other sites More sharing options...
