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.

Did you use a neutral grounding plug on your generator? Our EMS will usually but not always immediately block the generator from powering the trailer or charging the batteries. Not sure if your trailer has a built in EMS or not.  If you provide a bit more info, such as hull number, battery type, solar present or not, the forum members might be able to give you more specific help.  I hope you get this issue resolve quickly and it is something simple.

So, you have interior lights when the generator is connected, but no lights without the generator? If that's the case, I agree with @jd1923 that it sounds like your batteries are disconnected somehow. Could be a cable, cutoff switch, or 12v circuit breaker. More details needed.

Hull 1609, 2025 LE II, lithium with solar, and Yes used a grounding plug. Was successful FIRST time, will try again tomorrow, still learning The generator and trailer.
