For start check is there short between GND and :led + and - connection,spring,ntc and e-switch pads.I assume that you have ohmmeter/multimeter.

I’ll try, but I might not have said this. When I try the Eagletac battery, the light doesn’t come on when I START screwing on the body, but it comes on when I tighten the body at a certain point.

[EDIT: In other words, whatever is shorting is only shorting when I tighten the body.]

The other weird things is that if I then start UNscrewing the body, the light stays on almost until the point that I have the body completely apart.

Also, BTW, I did not attach the NTC at all.

Hi,

I found the problem! It was because the battery insulation was broken at a couple of points, probably because the battery tube is too tight.

I’ve posted details in the BLF TI thread (BLF Ti - post your pics and specs).

Thanks,
Jim
