Accel super coil 140003 question..

[67sss]

According to the instructions, I'm to the ground clip as it shows. I've done that but, my question is the ground strap on the coil inside itself goes to the other corner by the bottom plug tower on figure B. Does the unit ground itself on all four corners, cause the ground clip and strap are on opposite corners. I'm getting no spark, wondering if the ground is incorrect.
