Answer regarding http://forum.allaboutcircuits.com/showthread.php?t=58876 Why was this closed? The forum rules: OP never mentioned anything about an automotive modification. It was a simple question about a schematic which happened to be an automotive schematic. The purpose (as I understand it) for the block of automotive modification topics is to prevent people from making potentially unsafe changes to their cars, not to come down with the hammer of justice on anyone who puts the words "car" or "auto____" in their post. That is after all why there are human moderators, right? I'm pretty sure a web script could accomplish what I just witnessed. OP's question was already answered, but the principle of the thing bugs me.
