modifying modes on cheap amazon light

I got a couple cheap lights with 3 modes (low, high, strobe) and I would like to remove all but the high mode. I read about the pencil lead trick to short the capacitor but it did not work for me. I tried putting solder across the capacitor but then the light would not turn on at all. Luckily it still works after I removed the solder. What will happen if i remove the capacitor altogether? Are there any other things I can try? Here is a schematic http://www.datasheet-pdf.info/entry/CX2859 and a picture of the circuit board http://imgur.com/oSAtKFP Thanks

You can also try adding a resistor on the capacitor

“Have you forgotten about all those who called you a Bringer of Woe and hunted you like an animal?”
“Normal humans don’t go around killing people and burning towns!”
“Don’t worry. I’ll go with you! So you just follow me and no arguing, okay?”

 You can consider your self lucky ! Shorting the capacitor .., you just put your battery in parallel on the resistor (R300) , in the schematic this has the value of about 330 ohms so, only a current of about 12 mA .., what if that resistor was only few ohms ? A lot of smoke and possible a damaged battery !!!

On this particular driver you can NOT do " one mode only" , because the 3 modes are factory set in the internal memory (sometimes you'll find the same circuit with 5 modes ).

The only trick that could be done is to make it start in " high" every time , from off  , by soldering ,in parallel on the capacitor , a resistance , 47K...100Kohms !

Good luck !
