Just a thought about a previously mentioned problem. I disassembled this biatch and cleaned everything and there wasn't anything apparent to create this issue. Reassembled and it seemed to work properly again. for a little while. I ended up swapping atty's around and looking further into what my coils were doing. It seems to me that this machine is quite finicky. The "check Battery" warning most likely comes from a resistance that it doesn't like, so a different coil wrap perhaps, or it could be a very simple non contact issue with a leg of one of your coils. So look into the atty's as a first step. Like I said, it is a biatch of a machine that likes things to be just so. It senses the slightly loose coil contact and reports it as a "check Battery" issue to the end user.
