My lady's istick is having some issues, too.
If I put her aerotank mini on it, it does not detect it. I thought it might be the adapter dohitchy but I can screw my aerotank mega in and it works just fine(with and without the adapter). So she's stolen my mega!
Any ideas? I've cleaned the threads, tightened down the coil, backed the coil off, tried a new coil, I don't know what else to do.
