Z62 tailcap (A2/L1) fix?

[michaex]

I have an A2 that won't keep constant on with incan bulb, with tailcap fully tightened. Works perfectly with momentary though.

I researched old threads - couldn't find info if it can be fixed.

Has someone experienced such issue or knows how to fix the tailcap?

Thanks!

In case someone will be looking for an answer in the future: electronic part of the tailcap in my sample sits too far from the body when fully twisted. Adding an oring solves the problem. Now I need to figure out something thinner to get the body and tailcap markings close together as I'm 3/4 rotation too far out with current oring

I had a similar problem with my LX2, you could mash the button for high, but tightening the tailcap all the way down would not produce constant-on high. Slight manufacturing/assembly variations cause this issue between specific tailcap and body specimens.
I had to call Surefire and they sent me a replacement tailcap.

Thank you @sween1911 - I thought that might be the case.

I was told by SF that those tailcaps are no longer available - it seems like we're in for some home grown methods from now on!

I have the same problem with my a2. The problem with my z62 tail cap is one of the prongs broke off from use. I called SureFire last year and they were willing to take a look at it and send me a replacement a2. But it would be the new led a2 and they would keep my four flats. I haven't found a suitable way to repair my a2 as of yet.

Adding an oring solves the problem.

Any chance you can chime in and tell us exactly what your procedure is for this fix? I'm not quite able to picture the procedure, e.g. what size o-ring and where/how do you install it?

Unfortunately I no longer have the A2. In my sample nothing was broken off - after opening the tailcap it became clear that I needed to "push" the moving part towards the battery. My oring went on the 4th part from the left on the photo in this post. I hope that my non-graphical explanation will be enough for you!

Okay, I think that clears it up, thank you!
