Is my torch dead?

My low use BLF SE 18650 torch wont switch on.

I opened the clicky end to re-charge battery. After charging - no response from torch. (battery works fine)

I’d start with some simple troubleshooting tests:

- Did you insert the battery with the positive end facing the head?

- Maybe the head is loose? Try tightening the head?

- Try cleaning all of the metal contact points. Maybe there’s a piece of dirt that’s preventing the tail cap from properly tightening up and completing the circuit.

  • Try bypassing the switch. Use a piece of metal like a paper clip or tweezers. If the flashlight lights up, the switch is the problem.

OK. The metal clip as contact works.

But still no response from clicky cap.

Good, it’s not dead.

Check the retaining ring inside the “clicky cap”. Tighten it.

Try get another fresh 18650 to test on it.

I just “cooked” my driver >.<

Now when contacting the cap ready to crew down at angle it works.
When aligned with thread & screwed down - no response.

Still no light - officially. however when first holding cap to end ready to screw down the light comes on. But once I start crewing cap down contact is lost.

I got other lights but this one is my goto lite. What can i do?

Look inside the tailcap. Remove the brass ring with some Needle nose pliers. Remove the switch/spring/PCB assembly. Inspect the assembly. Check operation. Reassemble. Make sure the brass ring is good and tight. Make sure the tailcap is good and tight. Make sure the end of the battery tube that contacts the inside of the tail cap is clean bare metal. If it still doesn’t work get a new switch. 17mm omten 1288

Convoy sell ready-made 17mm Omten 1288 switch assemblies, should you need one.

EDIT: blast, I’ve just noticed that these are no longer available. Do you have a soldering iron? Omten 1288 switches are sold all over the place (Convoy sell 10 packs here for example).

I don’t trust myself to pull it apart. Bummer.

Pull it apart there is nothing you could break

Nothing to it ‘AaLF’, go for it. :wink:

Bend a paper clip to fit around the retaining ring of the switch. If it works when screwed together, you need a slightly larger shim in the switch assy, or thicker retaining ring.

If the retaining ring is too deep in the tail, you can bend some copper strand in round shape between the board and retaining ring
