Hello All,

New guy here needing some advice. So I am trying to bring my old 2AA Mini Mag back to life and it's not going well. Please note that this is all for purely sentimental reasons. I know I can get another one for like 15.00 bucks. But I've had this one for a while, and I want to keep it.

The background on the light is as follows:

I bought the light around 20 years ago. It worked great for a long time. At some point it got put into storage and it had the infamous battery leak. I get the batteries out. Soak it in Coca Cola and scrub it out. I order a brand-new switch assembly. New batteries and ordered a 2 pack of the bulbs. I install the new switch assembly and a new bulb, and it immediately takes off working. I play with it for a few minutes. Then it flickers and goes out. Won't come back on. The second bulb got a slightly bent pin. It would insert, but not come on.

I figure its bad bulbs, as everything else in the chain is new. So, I order an LED module from Amazon thinking it would work. It did not.

So, I'm at a bit of a loss. I'm thinking it must be some sort of a contact issue, perhaps? Or can past corrosion in the barrel actually prevent the new parts from working? Anyone have any tips on what it might be?

Thanks in advance for any help.

The critical part is the inner rim of the tube that the switch butts up against. There's a ring of bare metal the switch contact needs to have a good connection with. My guess would be there some corrosion on there that's keeping the switch from completing the circuit with the body tube. Take the switch out and have a peek down the tube. If it's hard to manually clean (steel wool, brass brush, etc) I'd soak the bare tube in vinegar for a couple days to turn the corrosion into paste.

This worked. I soaked it in vinegar. Found a brass barrel brush out of a gun cleaning kit and started scrubbing. Worked like a charm. My old mini mag is back in action. Thank you for the advice. Its much appreciated.

Awesome! As much as we love our super bright and efficient LED's, the beauty of old school incans is you can always get it running again with bulbs and batts.

I always has a Minimag around, great lights!

I know there is better out there, but I just love my old Maglites. And I did upgrade to an LED module for it. I've added LED modules to all but one of my Mags. Much brighter light now.
