All was working untill a Thorfire C8 hit the floor from about 1-1.2 meter, after that it wont turn on.
Test LED, working, switch working, driver probably is dead but I don’t know what can cause this more precisely what could go wrong ?
Also need one for replacement do anyone know where to find the same one ??
It is 20.7mm and board thickness is 1.6mm.
have you checked if the inductor has still connection?
usually the heaviest parts fail after a drop
My Nitecore EA11 stopped too after a drop, check this out:
Should be the same driver.
The RED wire looks burnt/damaged near the base.
It stand firmly, I do not have loupe but as far as I can see with my eyes all is on its place, there is a lot of small components so I can’t be 100% sure without enlargement.
I will check tommorow, go to sleep now, thanks.
Thanks, it looks like it is ! :+1:
No it is not burned or damaged, probably I cut it a little somewhere when removing a driver from shell.
I check with DMM and there is connection on both wires from top to the bottom.
That’s exactly what I was about to say.
Yea i would say its the inductor i have had a few break from AAA/AA lights in the past.
It is possible that the coil springs have been compressed from the fall and there is not electric contact.
I already order new one, but if someone have idea what to check and where to check I will try. I think this one is dead and nothing can be done.
I oreder this driver : https://www.aliexpress.com/item/C8S-5-Modes-Circuit-Board-Anti-reverse-LED-Driver-Chip-mode-memory-function-20-8mm/32813072001.html?spm=a2g0s.9042311.0.0.28794c4dNqHrWx
Got it, replaced but I have only one 100% mode :person_facepalming: On pic it say 1, 10, 50, 100 % and strobo…
Don’t know what is happening, first review comment says : ‘’wrong wire females припаяли seller look at the picture shown as there is correct, they дибилы припаяли blankly дросселю to and збсь so all!!!’’
Don’t understand what he saying something about wrong + and - but as I see all is like it should be :cry:
Check for shorts between the emitter/driver negative and the body/reflector. This will effectively bypass the driver and give direct drive whenever the tails switch is on.
Yep thanks I found a problem, open again and somehow when I put all together and screw up an retaining ring from negative wire is taken off some isolation so wire was naked and somehow touching something which causes a problem…
Also I get one new inductor, will try to replace on faulty driver to see can it been fixed.
I do not think the induktor itself is damaged. But because it is heavy it could have broken loose. try to resolder the leads of the induktor and check if the problem is gone.
It stands very firm, but I will try, it do not cost me nothing :+1:
