Probably would have been better if you'd started a new thread instead of adding a different issue on this one.
An RV can get 120 v A/C power from two sources, but alternating current can't be mixed. You might have an automatic transfer switch (ATS) that senses power source and switches from one to the other. If that switch fails to operate, power won't flow. An ATS switch is usually wired to default to generator power.
The second method used to select power from the two sources is an outlet and plug configuration. Look in the generator or shore cord compartment for a large outlet that your shore cord could plug into. In an RV without an ATS, to switch sources you change by physically plugging in cord.
