I have a modded Supbeam K40 which I bought a while ago off a member over on CPF. I think it has had the usual mods like braided springs, sense resistor mod?, copper star etc…
Anyways it has worked flawlessly until now, I went to use it tonight with freshly charged Panasonic 18650s and it turns on but is really dull almost like it is in moonlight mode and it is like this regardless of where I have the mode selector ring. Like standby and strobe etc all work still just with a really dim output. Any ideas what would have caused this? Could it have shorted somewhere? I did check the tailcap current a little while back, could i have accidentally shorted something then?
I haven’t used it since then, so I literally checked it then put it aside. Although when I checked it I didn’t get a reading so I am wondering if I put the probes in the wrong spot and shorted something.
But I wouldn’t have thought I could short anything if it was going through the DMM. Because from a tailcap I would be either connecting the circuit or not?
Place one ‘active’ cell’s + end touching into the dead cell’s + end (they should be facing each other then), then find a short wire to short the two cell’s negative ends.
