I have a Vertex magneto that I am installing on our sprint car and have a question. I have never worked with this type of ignition so it's new to me. My question is, the magneto cap has a direction arrow on it that shows the rotation. Does this arrow go towards the motor or the firewall or does it matter? Since the plug wires come out the side of the cap, I would like for the wires to be facing the firewall if possible. How does everyone have theirs? Pictures would be nice too.
