Aux Battery ? Newbie

[DJTimBit]

Hi, I have purchased a 2003 190 Roadtrek. My question is regarding the aux battery or more specifcally the fridge. Being a new owner I'm not able to get the fridge/micro operating using the aux battery. What am I missing? Thanks in advance for your help.

I doubt you'll be able to run either successfully on the battery; just not enough power. The refrig will run on 12 volts for a short while but will deplete the battery quickly unless the engine alternator is supplying power.

understood, the problem I'm encountering is the fridge is not working either AC or DC. Although it's 8 years old it hasn't been used much. I haven't tired the LPG yet...

Make sure the battery disconnect switch is on not off.
Check all the 120 volt breakers and 12 volt fuses,

Thanks for your help. Everything is in working order. I don't think I was patient enough on start up. Thanks again !

You might want to test your battery with a multimeter.
The deep cycle battery charge specs at rest, are available at various websites online, just by googling.
I think 12.7 V DC fully charged/at rest sounds about right, but I may be corrected. The alternator should
be charging it at around 14+ V DC when the engine is running. You might also want to check that with a
multimeter.
