Help please! Quark dead?

[BirdofPrey]

Late last night, I was hauling water and filling my cistern. While watching the overflow tube, my Quark Tactical 2AA (warm tint) started dimming rapidly to just about the level of "low". I thought that perhaps my batteries were dieing but didn't seem right because I didn't think I had used them for very long since the last charge.

So, I had my minix with me and went to that. Once I was done, I came in and since I didn't need it anymore I didn't bother putting new batteries in. Instead, I just pulled the batteries and threw them on the charger.

This morning, I pulled the batteries and put them in the light and hit the power button. Nothing at all. Pulled them out and made sure I had them in right and tried again. Same deal.

So, first thought was batteries were bad. Put new batteries in, same thing.

So... any suggestions before I attempt a warranty issue with 4sevens?

If there is something I can try here at the house, I'd prefer to do that rather than hassle 4sevens with it. I currently have purchased 5 lights from 4sevens and have had no problems with any of them until now so I can't say I question their reliability. Just odd that the light I use least ends up being the one that something goes wrong with.

If you have interchangable heads or tailcaps, I would start swapping out parts to identify what has died. If it's the head, you'll probably need a warranty replacement from 4Sevens. But, if it's a tailcap, it might be as simple as reseating the spring. A bad connection would appear to be low voltage to the flashlight and I believe the regulation will just shut the light off at that point.

I agree. You can also clean the contacts (threads, ends of battery tube, contacts on inside of light) with rubbing alcohol (isopropyl). If you don't have a tailcap a paper clip can be a quick substitute to rule the tailcap in as the problem. If the tail cap is the problem you can try tightening the retaining ring on the inside of the tail cap.

Sometimes the pocket clip retaining ring backs off just enough to not let the tailcap fully seat causing the connection issue, I would check that.
