Hi,
I managed to salvage a working condition power supply and desolder one of the choke (if I'm right the name of the component) as shown in the attached picture.
I tried to create a simple boost converter to see if I "boost" voltage above 3V using the following circuit (it's not my circuit by the way, I google it and found this is the simplest I could find)

My circuit is similar to the above except no switch, diode or PWM, just the choke, 3V battery and a 10uF capacitor.
To assist in measuring the voltage I add a dummy resistor load of 1k and measured the voltage drop but I can't see the voltage increases all I can see the voltage drop across the resistor as 2.6V.
I'm sure it's something that I did wrong, can anybody point me in the right direction.
Edit:
As there are 4 legs in the choke I connect leg 1 and 2 to the circuit
Thanks
