1 Tested all components in ignition system per ohm readings on YouTube video. all readable units were good.
2 Ignition control module (spark unit) was the only part that could not be tested.
3 Ordered spark unit
4 Removed four screws from control panel, disconnected one cable, removed one mounting screw and reversed t he process to assemble.

Testing required removing all panels and some disassembly (about two hours) still easy and reassured I was ordering the right part.
