Does anyone know if there is an switch we need to flip when using 120v power? We have had our camper plugged in to 120V power when garages in recent months and never had a problem with losing power....The camper has been plugged into shore power in my garage for the last few days and today I can hear the CO detector chirping and the outside yellow light doesn’t work, making me think there is no power. I tried to raise the camper and confirmed there is no power to the motor lift either.
The converter (converts 120V to 12V) should come on automatically. In the meantime, your battery is dead from carrying the 12V load. The propane/CO detector beeps when the battery voltage gets too low. The failure of your porch light (yellow outside light) is also an indicator of too low battery voltage.
The converter not working has a variety of causes. The converter itself is on a circuit breaker on the AC panel, as are the non-functional outlets. Makes me wonder if your AC is actually getting through to the camper. Does the microwave work? Microwave is 120V only, so if that's not working (clock flashing) when plugged in, it's an indication the 120V system is not getting power. Start with the AC side of the converter.
When that checks good, then move to the 12V DC side. DC power - both to run the camper 12V and recharge the battery - is supplied by the converter only when plugged in to shore power and 120V reaches the converter.
Otherwise, the battery supplies the 12V DC. In pop-ups and A-frames, Forest River (and most other brands) do not install a battery cut-off switch. When your camper is stored, and not plugged in, the battery dies within a couple of weeks from things like the stereo, the CO/propane detector, and anything else that does/is not turned off completely. Dead batteries happen frequently at RV dealers because they don't bother to disconnect the battery or keep the camper plugged in.
1) get a voltmeter and learn how to use it.
2) install a battery cut-off switch at one of the battery terminals for when the camper is stored, but not plugged in.
3) solve the AC power problem first, and then check the converter output
4) have your battery tested to see if it still holds a charge. Most converters will not recharge a battery if it drops too low.
I don't know your level of understanding of the electrical systems of your camper, so if this is too basic or too complicated I apologize.
