Problem with my MTE P7

landrew

I have just got a P7 light from DX which unfortunately does not work properly. I can get a short flash from the light by twisting the battery compartment but nothing more.

Does anybody know whether there is anything that I can do to fix this or do I need to return it?

Make sure the little bit in the cap which the battery contact is attached to is screwed in tight?

My battery gave up after using all of last winter. A few of my mates bought them as well, we've all had different problems - none have been trouble free.

Is usually contact problems: often can is as above a tightness and contact problem.

One of mine developed a slightly loose tailcap switch, to fix it I got a big paperclip and bent it round so that the "legs" fitted into the holes on the switch, then just gave it a spin. Yours is probably the same. That said, if it's DOA possibly best just to send it back.

Bloody hell, are you serious? I just tried that with one of mine that's malfunctioning, and the two little holes on the switch are giving way (deforming) before the damn thing turns at all, in either direction.

NO

For the price of a "decent" light, I could by about 10 P7 torches.

Try stretching the spring in the tail cap a little with pliers, it fixed a problem I had with the light flickering when going over bumps.

Yep, dead easy. That's how they're fitted I reckon. You need to keep the "legs" parallel so you need a strong bit of wire, otherwise the wire'll bend and collapse the edges of the holes I reckon.

He already did. Course, he could spend £300 for something that gives no more light, and is just as likely to get broken in a crash or suffer some sort of battery failure...

My first SSC light, now three years old has a similar problem, I used a piece of folded kitchen foil at the end of the battery, it'll probably go in the recycling soon.

No such problems with Aurora P7s though or the X2000.

They are just a few £ in any case.

Hmm. I'll have another crack tonight, but I reckon it must be threadlocked in or something, it just really didn't want to budge.

^This worked. Not been out with it yet, hoping to get out tomorrow. Very impressed with the brighness, fantastic light for the money.

Thanks for all the advice.

Hmm, it's nothing from the tailcap causing problems on mine.
Has anyone opened the front end of one before? It looks like it might be bonded, not just screwed.

WOOP!
Sorted mine. I used a massive spanner, and a set of pipe grips to open the front end, and found a loose connection.
After fixing that I found that the solder trail in the tail-cap wasn't making a great connection with the screw-in bit in the cap, so I'm going to solder a jumper between them.
Now I have two working P7s again.
