There are no wires, it's an Rx Machina mech mod, yes I know the batteries have been downgraded to 25A and the atomizers are @ .27 ohms and .28 ohms each with no shorts,
Maybe you misunderstood what I said. I know the Machina is a mech and has no wires. By checking for shorts I meant checking your RDA for shorts.
Are you making your own coils, or buying pre- made? Do you check them on an ohm reader or regulated mod, or do you take for granted that they ohm out to be what they are "supposed to be". Have you made sure that the coil legs are not touching the deck or RDA cap? Are you certain that the post screws holding the coils in place are snug and not loose?
If your RDA has an insulator, inspect to see that it is not damaged. That could be a source for a short.
I don't mean to be rude, but I can't assume on an internet forum that you already know to check these things. I don't know you or what knowledge/experience you have. Just trying to help.
