What size coil are you running? That would be bad @ 1.0 ohms, but not so bad at 0.2/0.3 ohms. Also Is your mosfet grounding out at the top metal piece or at the batteries maybe making contact to the box at the bottom on the negative side? Not sure if it would give an issue of being hot, but the only thing I know with mine is I make sure at both places nothing is making contact with the metal of the box and from your pictures you have posted you have the mosfet heat sink open. I always take my heat shrink all the way up to the top past that heat sink so nothing makes contact. At one time or another I had auto fires with one or the other. Not saying you are having these issues, I'm just trying to see the differences between your build and mine. Also the one you see with open copper wiring has rubber bed liner sprayed inside the box making the entire interior of the box non conductive. 0.1ohm dripper, I havent Installed It in the box yet, waiting to get it drilled. So at the moment theres nothing to short on. Glad i tested before install. Once its working ill insulate the rest of the mosfet |

Hmms I have never had my mosfet's get extremely hot when using. I use almost the exact same setup, but I use a 1/2 watt resistor instead of a 1/4. Was it an instant hot on the mosfet, like as soon as you pushed the button it got hot right away? Did it fire well? Light up the coils? Last 3034 mosfet build. Little bit more complex. It's series, and 26650, but basically the same set up on the mosfet.  More like yours. Parallel mosfet.  Hey Resnik, yeah It got hot straight away, had good fire on the atty. I checked the voltage across the mosfet while firing like vapingbad said and got 3.5ishV batts were at 4.16 so theres a fair bit of voltage drop somewhere. |

VapingBad yes thats how I wired it apart from I had 2 wire coming of battery pos+ going to 510+ and switch, so same thing. Multimeter is coming out at 0, but is zero when I put leads together aswell so I think its kaput

I am confusing Chegs with CraigHB, I know, I'm dyslexic, but you need to make sore the FET is completely on so you must have enough V GS (>= 2 V if I am reading the spec right) or it will try and amplify it, you probably don't want it too much higher, but I am not sure. If the voltage is wrong check all the connections, then we need to select a different value resistor to cure it. Which setting on multimeter? |

VapingBad ive got a major problem, ive just had a test fire of it to check I didnt fry the mosfet when soldering. Ot Fires! Woohoo! But the mosfet got super hot and branded its shape onto my finger. Ive checked my wiring against the diagram its all fine? Help?

I'm getting excited now Steve (VapeStorm) these updates are coming so fast I expect world peace for the new year. If I can get It drilled tommorow Ill be vaping it tommorow night. Going to a garage round the corner see if he could drill it for me, saves buying drill bits |

Just need to drill my box, 3 more solder joints then finito! Apologies I couldnt do a step by step, learning how to solder nd the frustration made messing with a camera aswell impossible. I have how ever got a shot of this evenings effort  |
