My Convoy stopped working, what's wrong with it?
Yesterday, I went to turn it on and nothing happened. I thought maybe somehow the battery fully discharged and somehow I'd missed seeing the low power blinks.

I took it and switched out batteries. Nothing happened again.

For some reason I can't find my nitecore 4-bay charger or my battery tester. Not too long ago I wanted to get those in their own special spot but I have no idea what spot that might have been and I have looked everywhere.

I want to double-check everything.

I suspect it's the flashlight itself and if so, what could it be?

It doesn't have an old-timey bulb to switch out.

SKU 1457700

edit I just found my charger right behind my sewing machine. I have 3 18650 batteries charging on it.

Doubt it's this because you have a spring contact. On solid chunk of metal type contacts, metal (probably zinc) gets transferred from the baterry to the copper and oxidises interrupting contact on the negative contact. A little polishing fixes it.

I just checked my springy contacts and both ends look as shiny and clean as can be. I've ruled out battery. I just put a completely charged nitecore in and got the same result, nothing.

:( dead.

If it's easy. I'd take it apart, fiddle around, then put it back together. Sometimes works. Not worth the effort if it's difficult. It's broken anyway.

one thing I'd try. Push the button and then screw the torch onto the base. Doubt it will work. That's more for fixing something that was interrupted mid process (appliances with micro-controllers)

Tried it but nothing.

When I remove the cap part I see 2 tiny screws holding the plate down that holds the led. I wonder if I can just buy that part and replace it?

just bookmarking these for reference. I should take it apart and look things over, measure, then think on it.

My flashlight: Color Temp Range 5000-6500K
SKU 1457700

These emitters (I couldn't find one that said 5000-6500K)

Cree XM-L2 U2-1A 1000LM 6500-7000K LED Emitter
SKU 5288900

Cree XM-L2 U2-1A 1000LM 6500-7000K LED Emitter
SKU 5288901

It's weird how they say 1000 lumens in the description yet they say

"Lumens (Max) 900 LM"

in the left column.

Good idea. There are lots of flashlight enthusiasts. They'll know what will fit.

Probably the heating/cooling cycles have stressed the solder connections to the emitter/module. Remove the lens so that you can get in and press down on the emitter with it switched on. If it bursts into life, it's a dry joint. If it doesn't it's probably fucked.

Try bridging the neg end of the cell to the (un-anodized)end of the batt tube with anything metal. If it works then, the switch might be bad/loose.

Btw, doing that won't hurt anything. (some people get worried)
I just need one more flashlight. Just one. Honestly. :D

Oops! I assumed it was a an S2+ with a tailcap switch.

Anyways, if you never unscrewed the bezel and it worked when you last used it, it's highly unlikely that it's the LED. Even if the plate the LED is mounted on is completely loose and hanging by the leads, it should still work normally although it will overheat very quickly.

MUCH more likely that it's a switch or driver problem. Side switch lights can be a hassle just to remove the driver, and the switch often has to be removed to reach in with something to "push" the driver out.

I'll see if I can find something online about the problem.

edit- You might need to have someone work the side switch while you bridge the cell/batt tube. It's hard to do it all with only 2 hands. At least it is for me. lol
