I think I found the post (
Atty problems)). I tried what was suggested, but still nothing. When I screwed the adjusted atty onto the mod's connector, it just pushed it back in. I just don't understand why in the world it's not working??? Batt is fully charged, mod is switched on and atty works on ego XL batt.
Well, that was step 1. Now, without a meter and some testing, this gets more complicated...
Let's assume, from your description, that the center posts are in fact connecting on that 3.0 ohm atty. Let's further assume (checking assumptions):
1) The atty is good since it works on the eGo
2) The atty is connecting on the 5 v mod
3) The 3.x volt eGo fires the 3.0 ohm atty.
4) The LR atty fires (briefly checked) while on the 5v mod
Something is strange to be sure. The LR atty actually draws MORE amps than the regular atty, so you'd think that it wouldn't work if the batteries were bad or the regulator was iffy. IDK if there's some threshold requirement, ..... you wouldn't think so. What TI chip is it? Does the mod have an adjustment thumb-wheel or small screw (pot) that you turn?
Does the regular atty get warm at all???? Put it on the 5 v mod and hold the button down for 10 seconds. Does it feel warm at all? Do you have a meter?
Note that it is remotely possible that the mod can only supply enough power to barely fire the LR atty and won't fire the 3.0 ohm atty. You may wish to try another set of batts too.
