Could not see a spark. Turned the lights down some too.
The black coil box has 2 wires that go to the engine case.
One directly to it, the other goes to it through the ignition switch.
Both test good continuity to the case.
Those wires kill the ignition if they are connected to the case. You kill the ignition by grounding it. Open the switch and test for a spark.
