Installed a Victron Orion-Tr Smart Isolated DC/DC charger and am having trouble getting the running lights on the camper to turn on. Lots of ideas rolling around my head, biggest issue I see is how I’m using an isolated DC/DC charger and how the lights are using a positive wire from the truck yet the lights are all grounded to the camper. I feel like I could ramble on about ideas and solutions but I’m just curious what others might have done to work around this issue.
