Yes I know that. I wanted to just measure standby current and maximum power consumption with my battery so I needed to uncrew the tailcap. It was just very tight.
Could you take a photo of the body and the inner tube? I just bought mine and I can’t seem to make mine work. Not 100% sure if mine is a first batch FW3A but mine doesn’t have the retaining ring on the tailcap. Looking at the 18650 and 18350 inner tubes, the 18350 protrudes more.
Tried to use the inner tube both ways and I can’t fully screw down the tail or the head where the thicker rim(bottom part on the 18350 tube in the image) is positioned at. I don’t know if it’s an incompatible inner tube or I’m doing something wrong.
Yes, my oring is under the lip on the smaller tube. I also tightened the tail cap first and it didn’t seem to do anything. Tightening it down just brings it to this.
Sorry I’m not sure what you mean by
Could you elaborate?
I tried to remove the oring from the lip under the inner tube and I can tighten it down further, I get a blink so i guess there is power but clicking the switch still does nothing.
Oh okay, so there is no beep to confirm the continuity when I click the switch. I tried to tighten it down more but I think it’s tightened well enough. Any suggestions to fix this?..
I just wanted to post some comparison photos that I took with the different tubes and clips and also side by side with the FW1A!
I really love these lights, did I mentioned it already?
Enjoy! BTW, all of these (except the Sony battery) was bought from www.nealsgadgets.com
Stuff I bought recently!
FW1A >>>>> FW3A
18350 tube
18500 tube
Tailcaps & Heads (FW1A has a retaining ring on the tail and the retaning ring on the driver is brass)
Tubes (FW3A > FW1A) [ yeah, they are different, but interchangeable, as far as I could test them and put them to work! Also, the clip on the FW1A is not dark, but it can be easily darkened with a blow torch, unlike the deep carry clip, that will probably take more efforts to do that! ]
Can you check if your retaining ring in the tailcap is centered and that the inner command tube fits inside of it? You can also try to put the command tube in first and then screw on the outer tube.
I tried it without the oring and it still won’t wotk. Thanks for all the help anyways
I don’t have a retaining ring on mine. I had the one without it. It’s aligned really well as far as I can tell.
The tail cap and head works fine on the 18650 tube so I’m sure the short tube is the issue
I tried to check continuity without the battery tube. There really is no beep. I think the inner tube really is just defective. Tapping at both ends of the inner tube doesn’t seem to beep either.
I wiped everything with IPA and yes they’re all bare metal.
