Two sets 180 degrees apart one for each cylinder, two points and condensers, two external coils and one charge coil. Not sure if that was their best idea.
No, low tension was surely not OMC’s finest hour for sure. More complex and less reliable than regular magneto. This system can be made to work satisfactorily, but requires much more maintenance that regular magneto. The key to success is keeping the mag plate from getting worn resulting in slop. Remember to replace that plastic bushing, 322435, on the engines that use it. I’m pretty sure this engine does not use the plastic bushing though…
Dan Anderson reminded me that this system came about so a small alternator could be added to these engines. CDII solved all these issues…
