Quoted:
Title says it all, I had it completely assembled with no batteries in it and once it was done curing I put the batteries in it and it worked just fine. I woke up this morning and now it doesn't work at all. Changed batteries, no fix. Can take the tail cap off and throw it on another light and it works fine. I take the head off and throw it on another light and it doesn't work. I take the head off of another light and throw it on the body and it doesn't work. I have no idea what's going on. None of the contact areas seem to be painted. I'm going to call SureFire in the morning but in the mean time I come here to see if anyone else has had this problem and if so how they fixed it. Much obliged. Air cure or heat? ETA- I just had something similar happen to me. I pulled a battery out of my Aimpoint M2, and when I put it back in, the Aimpoint no longer worked. I replaced the battery, and it still doesn't work. I've tried three different new batteries, and none work, but they do work in other devices. It worked, now it doesn't work, and there doesn't seem to be any reason at all.

Heat cure. And I even used a lower temp for a longer time to be safe. |

How low....?
I used to do 200 degrees when I did thermal cure, and was safe, but I was always rather paranoid. |

Bulb didn't just happen to go out?

My first thought was that perhaps the head was damaged by the heat, possibly brittle solder joint fractures -but that doesn't explain why a known working head would not work on the light. The only ideas I can come up with are to make sure the contacts are clean by hitting them with some very fine sandpaper and wiping them down with alcohol and to try bypassing the tailcap with something like a paperclip, hopefully that will help narrow down the cause.

All the threads are clean but I'll hit it up with alcohol and try that. |

Pics of contact points? Built up to much paint that's inhibiting the head to fully contact the body?
Rechargeable or throw away batteries? |

if you coated the inside or edges of the front or tail areas, you may have lost conductive contact. You may need to file some cerekote of on the contact points for the bulbs.
Can you take some pics of the parts separated? that'll give an better idea. Mark. |

I didn't take any pics before I sent the light back to SF. The light was completely assembled when painted with o rings intact, nothing got on the inside.
