Protection circuit on 510 PT?

[Charlie58]

I ran into a strange thing this morning.
I was cleaning some attys I think I didn't primer them enough last time they were cleaned and they developed that acrid burned taste quickly.
I used the dip in boiling water and swish method.
Blew them out good and repeated a few times dried them and let sit with paper towel inside to soak up excess water when drained.
Burned out the excess water then dripped a couple of times with vg no nic to clean out any residual flavors still in wicking.
started out with a battery and it didn't last through 1st one so I decided to use my pass through on my wife's computer.
Got through all three that I had left.
Then when I went to vape on one I got a few drags then no go on the atty. My first impression was that I'd managed to kill the atty.
Hooked it up to a freshly charged battery and it vaped like a charm.
Then I thought maybe my wife,s USB port didn't have enough power to charge it. Left on the USB on mine for the day and went to use when I just sat down.
No go then I removed the battery to inspect for swelling etc. None found.
Re inserted the battery and vapes like a charm.
Remembered this happened to me once before when I was chain vaping at the computer.
Maybe over heated pssthrough and it wouldn't work untill it was unplugged and the battery removed taking away all power to the passthrough resetting it?

My 510 pt does that every once in a while... It will go great then dead as a door nail. I just take the battery out & pop it back in and like new again. I think it has to do with the connection some how.

Yep the little battery turns out to be a pain in the foot. I just got through look ing through my box of parts and pieces..I'm going to do some more research and with what I have I think I can make my on 510 direct PT. However I think lately I think I have spirits around me , cause almost everything electrical I involve myself with has proplems with, TV, Radio, Microwave, Computer now my PT ..gona do it but after this period of time goes by..it happens every once in a while, but has been a while.
