So if the recall has been completed (picture from recall showing the cable change is attached), you should have no issue starting your engine if the chassis (engine) battery is charged and working/connected correctly; because this BCC recall moves the engine ignition cable to directly terminate on the chassis battery terminal of the BCC. This ensures that the engine is always physically connected to the battery and is not dependent on the chassis latching relay inside the BCC to be on and working.
Since you currently cannot start your engine, it might be a better/safer option to have a mobile RV tech come and help you determine what is wrong. I suspect your chassis battery needs replacement (especially if it is original), or soon will.
