Not sure if I have helped or made this worse. I loosened the side screw and it fell out. I attempted to put it back in, but there is nothing for it to bite on.
When I put it back in and held it, using a lot of pressure, it fired right up and I got several good tokes. That is not happening anymore though.
And Kempo, I kind of wonder if you are on to something because with the screw out the red light remains on until I take the carto out. If I take the carto out and hold the screw in, the light comes back on.
I am going to pick up a multimeter today because let's just face it, they're cool to have.
What next y'all?
