Smoked some wires today

A short involving wire S2 or terminal L are possible reasons why the starter relay did not work.
I checked resistance at the solenoid. Ground was kinda trash so cleaned it up. It was showing about 20 ohms. B and S were in the MOhms, Between the terminals (B to all) was 5 Ohms. Is that normal? My state is kind of on fire right now so progress is slow and my car is covered in ash.
