Delayed switch (closed for three seconds then open)
I have server that won't power up.
I found that if I connect a 50Ω load to the +12 VDC output of the power supply everything works fine.
I only need this additional loading for about three seconds.
I ...

The voltage becomes zero when the load is connected [closed]
This is my circuit.
When I connect the load of 10 Ohm, the voltage goes to zero!
The voltage goes to zero even if I put resistor of 10 kOhm.
