convoy l4 and s2 I ordered both broken :(

[SandwichKing]

Hello I wonder if anyone could give me some advice on fixing them with the l4 the electric switch broke and it just doesn’t work I don’t know how to explain it but where could I buy a replacement driver/switch xD. But with the s2 the tail cap switch is faulty so if you shake the light or bump it or just turn it upside down it turns off i have checked to make sure it’s all tight but nothing

[Ouchyfoot]

Tighten the retaining ring in the tailcap of the S2.

Since both lights seem to be faulty. Is there any chance there is bad connection to the battery??

When using flat tops, sometimes battery is just too short and there isn't good contact. It makes driver act very strange.

In case it is poor connection, you could make a small spacer with folded aluminium foil, or use a neodymium magnet.

I have the S2+ from the group buy. It works fine with a non protected cell. When I put a protected cell in, it acts bizarre - flickers, changes modes randomly, nothing at times, etc. If a cell is too long, is this normal behavior?

appreciate any input here, thanks!

Can you try the S2+ without the tailcap, using some wire to make the connection between the cell and body instead? I wonder if pressure on the protection circuit is the problem.

Does the protected cell functions normally in other flashlights? At any rate, make a loop with a paper clip and put in the tailcap and see if lights up normally.

yes, protected cell works fine in another light. Paperclip lit up light but appeared to still flicker and do random things, hard to tell. Thanks.

edit: don’t mean to hijack thread but maybe can help OP too.

Tighten the pill. Ensure is push all the way to the front, so that you will have more room to accommodate the extra protected battery length.

The paperclip loop is mentioned here:

Trouble Shooting single 18650 light (C8 and the DST tube light)

Among all the other things going on currently, two of my stock lights are acting a fool. Battery is dropped in, tailcap tightened down, light switch on… bleh, nothing, or a slight flicker and eventually nothing. Loosening the tailcap while still on as it reaches about 30% unthreaded the light seems to stabilize and modes can be switched, but any movement of the light will cause intermittent disconnects. Loosen a bit further tailcap ~60% unthreaded and it functions perfectly even with movement. …

Saypat it kind of sounds like it's shorting something on the driver by compressing the spring ?? I'd take a pic of it and contact simon my bet is he'll take care of you .

I tried another protected cell in it and it looked like it was working, or so I thought. It had L,M,H, Strobe modes but NO S.O.S. Once again it works fine on an unprotected cell, and both protected cells work fine in other lights! This is frustrating. Maybe I’ll contact Simon but what could he do??? Send me a short cell? I mean this light was only something like $11 I think.

thanks Boaz.

I’ve been abit busy and haven’t had a chance to reply but the s2 seems to be working fine now after I cleaned the contacts on the switch maybe it was just a coincidence but does anyone know how I could replace the side switch/driver on the l4? I can’t find them for sale anywhere

[Tom_E]

Did you take apart the L4? Is something actually broken? sometimes the driver twists or gets pushed back, so the switch is out of position with the rubber boot. You can fixe it by re-aligning the driver, and cranking down the retaining ring to keep it tight.

Yes I took everything apart(it was very frustrating getting those wires through the holes again |( ) but I think I pressed the button to hard and it’s broken,It doesn’t come back after you press it nor make any sounds. I will take it apart again later but for now I have just been using it stuck in low mode which is still better than flashlight from any shops where I live. Unless I pay the same as about 70 dollars for 300 lumens

[Tom_E]

Ohh - I believe you can find/locate a replacement mountable switch, may be tricky to find the right size, and not sure what's involved to swap it.

[Helios1 (Helios-)]

Pics of the broken switch? We can perhaps help locate a replacement.

[Tom_E]

Actually my icon is a L4 driver... Pics I have are here: http://s1054.photobucket.com/user/TomE2012/library/Convoy%20L4

I filed down the backside of the switch though, to better fit the piggyback driver. Originally it was squared off.

[leaftye]

In a way it would be better if you broke the switch on the driver instead of the button on the body because then you'd have an excuse to upgrade to a nice BLF driver.

Off topic, but I need to find some switches too. I can't find the little plastic SMD type that I've seen on flashlights on Digikey or Mouser, so for now I'm going to see about harvesting some out of old electronics.

Which switches are you looking for?
