Help with WA1185 light

Fivemega Copper Head
Fivemega G4 D26 SUNLIGHT w/WA1185
Fivemega 3x18500 C Body
JasonH BeCu Fat Tail

So in this host pictured, it will not light up unless I loosen the bezel all the way off, and the drop in just barely touches the side of the body. after ut lights up, I can then tighten the bezel back down, and the clicky works fine, but if I let it cool down, it won't start up again. I tried copper tape around the module, and nothing... it's like it needs more resistance to start it up?

I currently have the module in a 6P host with 2 AW IMR 16340's, and it starts up every time.

thoughts?

I have some FM1909 Bulbs on their way here to, and I can try one of them....

anyone?

thanks. I'll pick up some IMRs. I still could not get it to light using that tactic, but I threw in 2 AW IMR 18650's and an AW IMR 18350, and just hand completed the circuit with a tool, and it lit up fine.
The AW Protected cells I have are on the backside of their useful life I'm thinking....

IMRs worked good. Thanks!
