[Dagger Thrasher]

Yeah, just change the plug; I tried to desolder the the batt wires from the MM to change them once, and it was a nightmare. I think Castle use some kind of special solder, as it just refused to melt...it kind of "caked" up. I also nearly wrecked the PCB because of this, so unless you have a very good iron, try to avoid touching the PCB.
