PT Eos parasitic drain

[greenLED]

My son's PT Eos is sucking batteries dry. We put new batteries about a week ago, put the light away, and they're now dead.

Any ideas on how to diagnose/fix this? (other than sending it back to PT for warranty work). AFAIK everything looks fine inside, the board, etc.

:thanks:

No but just pulled out one of mine from the BOB and it has been there for months with LSD. Worked great so gotta think something is wrong. I would just send it back.

I experienced this in one of my Eos... a battery had leaked in it at some point, and there was a tiny bit of battery goo on the circuit board. I washed the board off under the faucet and it's been fine since then.

open and check drain,
but one rule of thumb: electrical switch --> drain
mechanical switch --> no drain
EOS - as far as I understand it - electrical pushbutton switch

when not in use, get a small sheet of paper between one contact and cell

Thanks for all your input.

I just washed the board and put new batteries. Will report in a week or so (that's how fast the new batteries drained).

green, can You measure the drain?

put cells in such a 3*aaa holder most cheap lights have, set multimeter to "low DC", connect + with some cable, set multimeter into circuit from negative battery carrier to "-" connetion of light.

Does it show any current flow?

Now that you told me how, I can try.

Ended up returning the light to PT; received a Rebel replacement unit.
