No power on 12 volts

[Roadtreking]

Have a 98 Roadtrek 200. I have power when using generator and plugged into 110 but no power running off the auxillary battery. Any idea where to start?

The previous owner had marked the generator battery positive/negative wires backwards, so when we installed new battery, we hooked it up wrong and it threw some sparks. Not sure if this has anything to do with it.

Do you mean the inverter is not working?

Do you know if the outlets are hooked up to the inverter?
I ask because not all the outlets are connected to the inverter.
Check the ATS -- Automatic Transfer Switch... this intelligent black box senses the source of power and switches the power to your appliances etc.

Please take some pix of your equipment. (labels and all)
Some of the early RVs do not have all the gadgets; we won't know how to help you until we know what you have.

Thank you for the response. I will pass this on to my hubby and get more info.
We drove the vehicle without the auxiliary battery and that's when we started having problems. Not sure if that has anything to do with it.

Look at the connection on the batteries under the hood . I had a similar issue and the termal was the issue

If you indeed hooked up the battery incorrectly you may have damaged the Isolator as well as the Inverter/Charger.
