Step 2Change the circuit
Once you opened the beast, you have to change the connections.
Before changing the connections, it had 2 positions:
- position 1: the crank powers the leds
- position 2: the battery (3 LR44 batteries) powers the leds
After it will have the following positions:
- position 1: the crank charges the battery
- position 2: the battery powers the leds
And now, the schematics, very basic:
I have inserted a led in order to prevent the capacitor from discharging to the crank. And it turns on when the capacitor is being charged. There are many instructables already that explain this, so many thanks to You people for inspiring me in saving my fake torch!

you could actually just seal the whole circuit or put the switch between the led and capacitor only. That way you could charge it live... That is how I did mine. Mine is really weak though... The dynamo delivers just 2.5 V and not that many Amps either. Did you measure your output? Sweet safe though ;)
