Charging my batteries from generator

[TxMN2020]

Have use my honda generator to chargé our batteries 2 times nów, today being The second Tim’e, disconnected from generator, went inside to verify they full charges, and no Lightning or Power to anything on The master control at The door. Went inside when i initialy starter generator and had Power at than time. My FIRST attempt about a month Ago , same routine and no problem. We had our trailer winterized when we picked it up SO no experience with it SO far other than using generator to keep batteries chargéd. Recommendations when to start looking.

Given you did not work the winterizing, did they disconnect the batteries or do you have a cut-off switch for your batteries. No interior lights either? Hard to be sure from your description but it appears you have power connected to the generator and none when disconnected.
