Got an electrical issue on one of my 455 cars I'm trying to figure out, posted it in the electrical section of this board: http://www.v8buick.com/showthread.php?297106-Pertronix-Ignition-Issue&p=2459030#post2459030 Lets try to keep the discussion on this over there - I cant keep track of two threads! Tommy, you and I started messing with this when we found the coil was bad that one day. So I made a little more headway that confuses me.... Thanks in advance for all your help!
