Battery was full but machine showed it was almost dead. Replaced the processor, reset something and cleaned it out... It was covered under warranty so no charge too. It's a DFX 300 so it came with the super 12 coil. Interestingly, I never use it. Might have 3-4 times when I first got it. Was told to send it back w the original coil. Centerville said the coil was bad too and replaced it.
