I have a 912ul that I am trying to do my first start on. I have had a no sark issue. After testing the stator per heavy maintenance manual and testing voltage on red wires to ignition modules while cranking I had no power to the modules. After replacing the stator I now have power to the modules but still no spark. I may be confused on how the ignition grounding works and I am thinking I need to flip the switches over for proper operation but I have tried starting grounded and ungrounded and nothing. Correct me if I'm wrong but grounding the ignition modules shuts them off? I bought a spark tester and tested both circuits A&B by placing the tester between the spark plug ignition cable and spark plug. I verified the tester worked on another engine as well. Right now I am thinking I need new ignition modules but seems weird that both A&B are not producing spark. Is there something I am missing?
