12 volt system not working on 2011 Winnebago Vista

Hi,

I had a similar issue on my Brave, while connected to shore power all was good, off shore power no power, not even enough for the lights.. I found the issue to be a blown 12V fuse on the power converter. Though I did not know it was there. I found it when setting up a mouse trap under the galley drawer. Pull the bottom drawers out and see if you can locate the converter, then check that 12V blade fuse! hope it helps.
