@nofearek9

i retested today the tailcap readings ,used 2 set of batteries one was aw imr and 20R samsung and the other 2 notebook batteries, i got from both 1amp on high 0.5 on med and 0.25 on low
have in mind now i have moded the flashlight with xpg2 on copper pcb

Hi,

Thanks. Can you check one more thing? If you have a chance, would it be possible to get a picture of the driver showing the area around where the red/positive emitter lead and the toroid leg are, where the picture also shows the orientation of the HX-1163C labelling? See my post at Anyone worked with either of these drivers from Lightmalls? to see what I’m looking for.

Basically what I’m trying to find out is:

If you hold the driver board so that the HX-1163C labelling is at the top and upside-down, and then look at the pad where the toroid leg and the red wire go into the driver, which of those (the toroid leg or the red wire) is going into the hole/pad on the left, and which is going into the hole/pad on the right?

Thanks again,
Jim

P.S. Do you, by chance, have a way to measure emitter current, either with a clamp meter or maybe putting a meter in series with the emitter? I understand that the answer will probably be “no” if you don’t have a clamp meter…

EDIT:

NVM the above, I think that is a false alarm. It looks like the two pads where the toroid leg and the emitter lead go to are shorted together anyway, i.e., so it doesn’t matter which pad the toroid leg and the emitter lead are soldered onto :(…

EDIT 2: Any possibility you can measure emitter voltage?

EDIT 3: Sorry for all the edits (and question), but would it be possible to move the coil like in this pic and see what the value printed on that chip that has “R200” on it in my pic:
