@thedoctor50 not sure what this mod is or what it is supposed to do. All I know is that I am not fond of mods and it is possible that something got shortened out by either the soldering or the long leads. If nothing else, double check your solder work and the run of the cables. I would suggest that you start off by removing the mod and then re-evaluate. If it is still the same after, you'll need to check your board for any short as well as the ODD itself.
