I meant to clip off a C9 off a string, strip and tin one end, insulate the other somehow with liquid electrical tape/nail polish. Then wire it inside the enclosure to warm things up like Jim said. Unplug F16, loosen the AC connector, add the C9 wires, tighten. There should be plenty of room. All this being said, I am not entirely convinced your problem is a temperature issue. I see alot of low temps and never had this with Falcon gear. I have had a PS go wonky in cold temps tho. If it is temp related, the hair dryer is not the way to go. You drag it out there and warm it up/you freeze your can off as you now realize this will not be fast as you never dry your hair in subzero weather
and then it finally works fine but then an hour later, fails. The C9 should be easier and is the long term solution for temp related controller issues. I had to do it on all my DLA LE's. Agreed, doesn't seem long ago, Jim.
