I have a Sigelei 150w that is not acting right. When I take a hit it will jump Ohms. The build that I have I it now is at 0.3 normally but when I take a hit the next one will jump to 0.7, then to 1.0, 1.7, 3, 4.8 then it will drop back down to 0.3 for 4-5 hits befor ramping again. The numbers are not exact every time that was what it did this time. I have done strait wraps,braided, and parallel builds in it and they all do the same thing. I have had it about 6 months. Should I open it up and see if any juice got on any of the contacts? I have a mutation x V3 on it if that helps at all. Thanks for any help.
