2017 Roadtrek Mercedes Ecotrek system problem

How handy are you? Do you have a digital multimeter with you (and are familiar with using it)? Is it just all 12 volt systems, or is it 110V, too? Your Ecotrek has a large lithium battery bank, right? If you have a meter, are you getting 12V output from the batteries? If batteries have 12v output, but no power to any components, then master switch may be the issue, not letting power to your converter, which is the fuse panel for all systems. Our previous Roadtrek had a relay that was operated by the switch, the little push button simply activated the relay. not sure how the new Ecotrek is set up... You could test and see if you have 12v power coming into the converter. It may be something simple like a blown fuse or loose cable to the converter. I imagine you can find someone who could do some basic troubleshooting without having to drive all the way back to Fairbanks or Anchorage... Wouldn't even need to be an RV shop. Ask at the campground - bet they will know someone who could help diagnose the issue. Good luck - keep us informed! ST
