You can put the diode before or after the resistor, it doesn't matter,
but check the diode orientation. What you can do is to mount the
resistor and diode vertically by unsoldering one pin of the resistor,
putting one of the diode's pins in it's place, and twist both
remaining pins together. I think it's better to keep the resistor
soldered as it prevents the battery from being shorted, it will
probably reduce the circuit's consumption a little bit, and protect
the battery if the diode ever shorts for a reason or another.

I'll try to take a picture of what I've done in my SX240 this week.

I am just trying to clarify as I have been told several different things which are different, one person told me to remove a diode, another told me to remove a resister, now you are saying keep the Resister then add a diode between the Resister and the Battery? Correct?

>> > Does anyone have battery replacement procedure?? Can I replace this NiCad with a 3V Lithium? I have heard yes but also need to remove a diod so that the Lithium does not try and take a charge. I just picked up a SX 240 and it is perfect even the NiCad loooks ok but I do not want to leave it in there. The DX7 has some nice step by step pics for Battery replacement, I was hoping there was one for the SX240?
