Properly discharge a psu before opening? - Page 2

post #11 of 15
Thread Starter 
yeah, I didnt touch anything, and the machine it was connected to prior had been off for like 5 days, not that there cant still be juice, but when I did the fan test nothing happened. I dont know if its because it was wrong and nothing would ever happen, or if it was just fully discharged on its own. I know jumping the psu with it plugged into ac voltage would start it, but not sure about using the same method to discharge

oh well

the capacitor will not hold enough charge to make your fan spin.

it will slowly discharge over time - > this is the only real safe way for the normal person, unless you have high end lab equipment.

It's safe to do that, that will also pull off almost all of the charge stored in the caps, but it won't always get everything.

for future reference, what could I have done using a Multimeter? I have an old one, I forget the make but the model is AN 77. It works but I am not too keen on using it and I dont have the instructions. I get the concept but I dont have the details. I am a simpleton when it comes to electricity beyond simple circuits and soldering.
