Try THIS paperclip bypass to test the head function. Loose bezel modes get their negative ground through the threads, tight bezel modes get their negative ground through a combination of the threads and the outer brass ring on the PCB, so use a rounded end on the paperclip to connect both simultaneously.
If the head works fine, it could be a loose screw down collar for the pocket clip, or a loose clicky retaining ring (tighten w/needle nosed pliers), or dirty clicky contacts (open it up and clean).
This is excellent advice, also try a Scotch Brite pad from the kitchen, but don't reuse it in the kitchen. Or, a pencil eraser is an old trickDefinitely sounds like you are dealing with contact issues still. In your present state, you just need to get the end of the tube to make contact to the outer trace inside the head. Sometimes just cleaning has not been enough for me. Try putting a fine piece of sandpaper, preferably something like 320 silicon carbide paper, if you have it, on a flat surface. Then work the end of the tube on the paper. Back and forth, twisting, whatever. See if that gets the turbo-strobe modes back when tightened. Just a wipe with alchohol (or Deoxit if you have it) is all you should need for the trace on the PCB in the head.
LOL.. love it!btw, Ha ha, Suefire. :nana:
Excellent! [emoji14]arty: One would really hate to lose the use of an irreplaceable Quark.
Last Wednesday I received all the parts for a discontinued Quark Turbo AA2. I'd wanted one for quite some time but didn't have any luck on Panjo or the Market Place. FourSevens.com put all the parts on clearance. [emoji14]aypal: When they arrived I experienced the same issues recDNA did with his. A call to FourSevens, a little investagating by T J and the problem was solved. Seems the new head doesn't work with the old bodies. The new, new body should arrive any minute.
Thanks T J & FourSevens for the great service. :twothumbs

Good to hear all around, these lights are pretty tough - it usually turns out to be simple connection issues. Closest I've come to a failure was a Turbo 2L that I dropped half a dozen times on asphalt - light went dark on the last drop..... turned out to be a protection circuit failure on an AW 17670.
Surprised to hear any Lego incompatibility, I have new and old heads and everything in my collection seems to Lego fine.
LOL.. love it!
Quarks deserve to be used imo but then you never asked my opinion! LOL
Indeed! The thing is, I've been spoiled by my QP2L-X. It's really hard to leave at home. Besides, it's not like I bought all the AA2 Turbos and every once in a while, I need a fix. I will use it, just not going to put it into EDC. Feel better?
Absolutely! Makes a good kitchen light. I still use an old javevin with P60 drop in.Indeed! The thing is, I've been spoiled by my QP2L-X. It's really hard to leave at home.
