Re: Red OMC coils

With points the spark..if wired wrong..can jump from the ground to the center electrode…

My ’76 13.2 omc has n-s and then s-n and uses a driver coil to the spark coils on each end of the driver coil. My Atoms were both wired the same..did not need to reverse leads on one atom. ..something about the right hand rule in mag flux and current direction. If one coil wound one way needs n then s. Wind coil opposite and it needs to be s then n to maintain same current direction.

I think…as the Atom sees the voltage raise there is continuity to ground. At some point the mags move on and the voltage starts to drop. When the Atom sees this it quickly opens..causing spark at the plug.
