20 Most Recent MagLite Rechargeable Flashlight System Questions & Answers

Alot of maglites are problematic with symptoms like this... I have found that the culprit many times is the screw cap on the bottom of the flashlight.
The elecrtrical connection needed between the spring in the end cap, the threads on the cap and the threads in the barrel of the flashlight...
Make sure you twist your spring a bit..the dissimilar metals can actually corrode between the spring and the cap... Then spin the threads a little... Then try the flashlight again...
This procedure may save yourself replacing a switch..

These are notorious for the switches failing. Mag will replace it for free if you ship it back to them.

There's not much that can go wrong with the switch but things do happen.
I can tell you how to remove the SWITCH then you can go to www.maglite.com to order a new switch if you then think that's what the problem is. However, I do not know how to actually 'test' the SWITCH itsself to determine if it is defective. I have the rechargeable model which is nearly 20yrs old and it developed the same issue about 10yrs ago. I simply removed the old switch, ordered a new one, installed it and now have a happy light.
Let me know and I will send you instructions. :)

You've introduced two variables to your flashlight, and each needs to be tested independently. It's possible that one--or both--isn't working properly. It's equally possible that one or both of these replacement parts isn't perfectly meshing with the conductive areas of the maglite body, meaning that they're not completing the basic circuit needed to power the light.

The best way to test your tailcap switch is either to try it with another maglite or test its continuity with a multi-tester. With the tester, you should be able to toggle between readings of infinite resistance (switch off, no circuit) and little or no resistance (switch turned on). If you're stuck at infinite resistance, there's a problem with the switch.

You could test the LED insert by using test clips to touch power to the module to see whether it will light up.

My guess is that the components are probably good, but that somewhere along the line, there's a break in the basic circuit. My leading suspect would be the connection from the LED module to the negative (flashlight body) side. It could be that the module is slightly out of round and it's simply not making contact. It could be that the finish of the maglite is acting as an insulator. However, I would recommend deferring this analysis until you've confirmed that each component works fine.

Good luck!

And your question is ...

Has the battery gone dead? replace it

Has the light burned out or otherwise gone dead? replace it.

Take your Mag to the hardware store and they will help you get it going.

you would probly need to get a new battry becuse u might not have engogh juice in the old battry any more

Stand it lens down and squirt WD40 down the gap and leave it standing overnight. That is the way the head comes off. My guess is that it is binding on the o-ring.

the spring has gotten weak that keeps the batteries tight together

It would be best if you visit the official of Maglite. It has all the required information which will solve your queries. The site has all the categories like spare parts etc.

This is the easiest answer I have found to date . Go to ; http://maglite.com/ and click " Support " . Follow the links from there ! Good luck . Alec .

Hello, you can find some video on youtube. https://www.youtube.com/watch?v=G8wmQKgOk7U Just type maglite dissasembly.

I'm gonna catch it for this but this is how I did it. Corroded batteries in the cylinder will eat and seize the aluminum threads on the end cap and it's pretty much toast after that. What I did was drill, yes drill a 0.125" (1/8") hole exactly .25" (1/4") above the seam between the end cap and the tube .0125" (1/8") into the tube. No more than that or you will jeopardize the integrity of the waterproof factor. Drop one drop of a quality penetrating oil, or even diesel fuel, into the hole every hour while randomly tapping the tube with a metal object to create a vibration to help the penetrating oil travel throughout the threads and dislodge the corrosive hold on your end cap. It might take a couple of days to loosen it up and try it with your channel-locks and a lined vice or strong wife. Just plan on gaining 1/32" movement and go back and forth until it gives up the grip. That process might take another day too. Keep adding the drop of penetrating oil along with the tapping religiously. It WILL work provided your patience holds out. Don't force it... well, not too much anyway. You can actually save it this way.

yes the bulb assy can be removed as it's basically the switch you need like a special tool for removing it. but first which brand of battery is in it. both energizer and Duracell have warranty about replacing item that the battery has damaged. try that route is my suggestion before trying to remove batteries and possibly breaking the switch. you can get one sent to you by calling up customer service as i replaced one before mini mag lite also.
