1590g Mosfet box, need help, tried everything i know of...

[deftonerdad]

Built this and have tried so much to get it firing correctly. No idea whats wrong. As you can see in pictures the 510 is getting the correct volts. the mosfet gets warm when you fire it via switch(like its suppose to). but not one atomizer will fire on it. tried 2 orchids, kayfun and a kraken all nothing. Any help would be damn appreciated. Been stuck on this hurdle for cpl weeks now and need outside opinions. and yes i suck at soldering i know this

 

[deftonerdad]

2 positive wires attached to fire pen. 1 going to battery+ and other to switch attached to mosfet.

Are you sure the atomizers are making connection with the 510 pin?

 

[deftonerdad]

pretty sure cause the 510 pin lowers as i tighten the atomizer

 

[deftonerdad]

even tried unscrewing the pin on the orchid a bit with no luck

 

[deftonerdad]

gonna wire up another irlb 3034 mosfet and see..

 

[deftonerdad]

new fet same problem

 

[deftonerdad]

also i know the 510 works because i removed the mosfet and when i would touch the bare wires together it would fire the atomizer

more pics ...the 510 gets power?? i have the mosfet wired as from left to right. G D S

Did you buy your mosfet from Mouser or Digikey?

 

[deftonerdad]

neither ebay.

 

[deftonerdad]

2 different vendors

serial on new ones is.....
irlb3034
6u f5
i r 425p

 

[deftonerdad]

does the p mean these are p channel??? Should i order from mouser or digikey instead?

measure the voltage while the atty is attached -- what voltage does the back side of the 510 show?

sounds to me like its getting shorted out somewhere.... if the transistor is getting hot its putting the power somewhere on the otherside...

(or you wired it backwards but im assuming thats not the case )

that is a n channel losfet for what its worth -- so something else is the problem -- check to see if your 510 is shorting out with your atties or something...

you do realize that the metal tab is electricly connected to the center pin too right? make sure its not shorting out somewhere...

thanks for the reply buddy! I took the mosfet out and just straight connected it and it works perfectly. def something to do with fet. I had it wored exactly like fred from findmyvapes. But I have a 20amp switch and i never go under .4 when vaping so im thinking of just leaving it out, got so frustrated last night i gave up lol. really appreciate your time

 

[david4500]

neither ebay.

It's possible they could be chinese counterfeits

 

[Trickydick666]

What seller did you use on eBay?

 

[Uncletattoowhat]

Are you running a 15k ohm resistor across G and S?

 

[deftonerdad]

Ya im running a 15k 1/4 watt resistor. Ive literally tried 20 different n channel mosfets and none have worked. I bought from a few venders on ebay cant remember. heres some more pics to see how its wired

 

[deftonerdad]

and just test the 510 for power with and without an atty attached. It gets power with no atty attached but when i screw the atty onto the 510 it gets no power?
