Awesome. Thanks for the update and I'm glad to hear that worked as I almost had to do that (turned out the PTC heater needed to be replaced, not the fuse).Snow, all good. Thanks for your response! All good now, I found the problem. I got distracted by kids and left the ground wire VERY loose. I’m back on the road with all system go.
I changed the PTC heater fuse in the DCDC.
