What's the tip going on, and how to fix it?
thank you for your answer

Welcome to ECF!

What type of box mod is it?

 

[dc99]

Since you titled it mosfet Im guessing its a mechanical box? Sounds like an auto fire. What mosfet are you using and what is connected to what?

 

[suprtrkr]

Is it possible you are putting the batteries in wrong? If you put one battery upside down in a parallel box, the cells will dead short against each other...

If you take out the coil and batteries, there are only three components left.
All can be tested with a multimeter in Ohms mode.
The switch should be low Ohms when pressed, and high(open circuit) when not pressed.
The 15K should measure 15KOhm, measure at the pins of the mosfet though.
The mosfet should read high resistance (open circuit) at drain source.

Mosfets have a bad habit of failing "closed"... in other words, the gate fails and the drain and source no longer have the abiltity to insulate from each other ( the holes arent there)... get an atty and remove the coil and replace the batteries and check for voltage at the + and - posts of the atty while the switch is off, if you get a reading ( +1V or higher) then the mosfet is bad
