Just got a pair SSC P7-C torches fromDeal Extreme. After one ride, bar mounted, one has developed a flicker on full power setting. Then it dims almost completely and sometimes fires up agin and sometimes dies.

I've emailed Deal Extreme re a replacement, but is there anything I can do to revive this P7 myself?

I got a tip from a guy on the Singletrack World forumin the uk to check the tightness of the diode mounting screws, they both seem tight. Could it be a switch failure?

Thanks in advance

i believe there was another thread on this issue and the result was that the battery may lose contact with the spring on the tail cap..you can use a spacer to make the battery fit in tighter.

I'm unsure if they are describing the same things. The linked torch was changing modes as the intermittent battery connection was acting like a momentary switch.

The way this torch is described, it sounds a little different. Is this a multi-mode torch or just on/off? That will probably be the key to solving this one. If it isn't a multi mode, then tkblazer is probably right on the money.

I had the same with my P7 and it turned out to be the battery. I used a friends and it worked fine. Got a replacement and it's working really well. I use it on the helmet and really puts my Hope HID to shame.

I had a similar issue with a torch from DX. I have the MTE P7 as well as the Aurora P7 one. The MTE works great but the Aurora was working fine until I took it on a first ride. Five minutes into the ride it died. I thought it was the batteries and replaced them on the spot but that didn't do a thing. When I got home I shook the light and it started working again but then it would just die. It worked a few times when I would unscrew the tail cap and screw it half way in. As soon as it was screwed all the way in it would die again. Then it stopped working completely and I just sent it back to get a replacement from DX; takes a while but they pay for shipping both ways.

If I had to guess, I would say my problem was the switch in the tail cap. I took the switch out and checked it but it didn't look like there were any loose connections. I have the 5 mode versions on both. The switch seemed REALLY CHEAP though. You can get a pack of them on DX for like $5 for replacement. Just take some tweezers and unscrew the tail cap insides if you want to pull it out and inspect it. Good luck.

Edit:
Oh I took the led with the heatsink out as well, didn't look like it was broken but didn't seem to be built as cheap as the switch. :) That's why I'm blaming my issue on the switch, for all I know it could have been the LED driver.

....Yeah, my MTE P-7 had the same problem...cheap clicky switch. When I get a chance I mean to write D/X to keep some replacements on hand.

Hi pete
Sorry but I did not explain myself very well about the diode assembly, the Diode is mounted on what is basically a piece of threaded bar. when you take off the lens assembly and you look at the diode I put 2 screwdrivers into the diode screw heads so I could tighten the whole diode block within the tourch body (so it does not rattle)

That sorted my problem
