Ignition switch is

I might have some time today to take old switch out for inspection. But even if I fix electrical contacts, the tumbler is pretty wear out and I think screwdriver will turn it.
So putting new ignition switch would solve few issues in single job.
My generator is not charging, at least per the ammeter and having spare VR I plan to put it in. Anything else to observe?
