Hi and welcome to Ninjette!
You did great job documenting wiring and what you tried.
Where are you getting info on hooking up resistor? None of those configurations are correct. Would blow multiple fuses.
1. Reverse all your mods and restore ignition-switch wiring to 100% stock condition.
2. Pull ALL fuses, including main 30a fuse and measure them. Replace any fuses that doesn't conduct electricity.
3. measure battery voltage with everything off. Voltage = ???
4. measure battery voltage during cranking. Voltage =???
