I have a brass praxis and Tobh v2. I was getting very high voltage drop so I cleaned my whole mod with Brasso and boiling water. I even have to get a new toothbrush because I used mine to clean all threads. So my mod is clean. But still with a .2-.3 resistance build. My voltage is reading 3.23v when fired (measured at the post screws ). Without a coil I'm getting 4.18v at the posts. Anyone have any clue or idea as to what I can do to solve this problem?
RDA Around 1v Drop!?!

Also I had a 4wrap 24g 1/8parallel when I measured those voltages. Rewrapped with a single 3/32 5 wrap and got same voltage drop....
Only problem I can seen is in the praxis button because I don't have a Allen key small enough to take it apart and fully clean it
i have a few small wire brushs that are good for cleaning threads without the need to clean the whole thing, a little bigger than a toothbrush but you can clean the bottom of atty's, contact threads, can even get into the female part of very small threads by wrapping a thick elastic band around part of the brush.
some batteries are also better than others under load.
when i used to do vd tests i would use a 1ohm coil, to many things can make a huge differance in the resulting reading when using higher power

While it may not be the whole problem as coil resistance drops and power increases some metals will actually raise resistance.
One of the first tests I would do is meter the mod itself with no atty from pos pin to neg threads with the button pressed.and see if there is resistance in the mod somewhere, it shouldn't be very high at all if it is clean and working.
I would then check the atty from pos post to pos pin in the 510 w no coil then with a 1 ohm coil test from neg thread to pos pin in the 510
then I would put it all together with a 1 ohm coil and check the v again
You have to eliminate each part of the chain.
Then drop resistance slowly and see what changes.
if it all seems correct I would try a different battery some batteries sag bad under heavy load.

you said it far better and more detailed than i was going to say. basically, OP, there are many areas of conductivity to consider- the whole mod is a circuit. and lowering your resistance doesnt always get you more wattage due to the fact that lower resistance builds often raise the voltage drop.
