Nope I jumped the two wires like you said and the ignition button still didn’t do anything

Did you measure voltage along path? where does it stop?
Don't skip steps. Here it is again. Give me a voltage reading at EVERY step along path.

battery +terminal -> ??? voltage?
30a fuse -> ?
W wire at ignition switch inlet -> ?
BR wire at ignition switch outlet (switch ON) -> ?

leave ignition switch ON for rest of tests

10a IGN fuse -> ?
BR/BK wire -> ?
Y/R wire inlet stop switch ON -> ?

stop switch ON for rest of tests

R wire outlet wire stop switch-> ?
BK/R wire into start button-> ?
BK/R wire out of start button ON -> ?

rest of these tests with start button pressed ON

BK/R wire at inlet diode B -> ?
outlet diode B at BL wire -> ?
starter circuit relay outlet Y/R -> ?
Y/R at starter solenoid -?


Important thing I'm trying to get across is critical-thinking process of troubleshooting. Not quick-fixes like "swap these parts" and it'll work. You have to understand why it's broken first, then fix is apparent. MOST important piece of data is where +12v stops in chain. That's only thing we need from very beginning. Once that's known, fix is easy.
