Mosfet box won't work

[scott_gliniany]

Hi folks, I'm hoping that someone can help me here.....posted yesterday but not sure it was in the correct section



I ordered lots of parts etc and made my own wooden enclosure. 2 of the parts I ordered were off eBay and were 2x IRLB3034 mosfets. First build was just like my first (working fine) metal box build except only a single 18650 instead of 2x18650's in parallel.



The box is not firing at all. I have checked my wiring and continuity of all my connections and they are good. But when I install the battery, the rda or kangertech mini tank are not firing. What I'm finding incredibly strange is that the voltage directly across the pos and neg parts of the 510 connector is reading around 3.9 to 4V when the button is not pressed, and 4.19V when it is pressed.



I would have thought that the mosfet was faulty but I tried the other one I got and the same is happening.



Any ideas? It's driving me insane!!!



Thanks in advance,



Scott.

Check your Mosfet and 510 wiring. Failing that, take the whole thing apart and start from scratch.
