New owner battery install question.

Installing a battery in our travel trailer and I'm not sure I've hooked it up correctly. After install the lights work and radio work but none of the ac outlets are working? I'm not sure if this is a polarity issue or if I don't have the correct battery to be able to power the AC outlets?

Sorry for the lack of noobness but hoping to get some guidance and advice.

I have the positive and negative lines hooked up according to the manual but the the smaller gage red and white wires, I'm not sure what those go to? Any suggestions?





this is the battery that was recommended to me?



thank you in advance for any help.

    X2 Sounds like you have it right, just need shore power for the outlets and major electric, like Microwave and AC.

    Smaller wires may be for power jack.

    Wow! I feel stupid. :|

    I didn't even think about that. yeah, I guess I will need to put in an inverter for 110.

    thanks for the quick replies.

    any ideas on what the smaller gage red and white wires could be for?

    Double check your manual and look at your reverse polarity fuses.

    BLACK is typically positive in the RV world, not negative. I believe you have both your positive and negative cables both connected to the negative terminal on the battery.

    White is negative, black positive, red is non standard positive for an RV.
