No DC from converter
I could write as lengthy a post as I tried to chase down why I had no DC from the trailer alone.. Everything worked when hooked to truck 7 pin or shore power. Nothing worked off the trailer battery alone.
I finally removed the red battery disconnect key and blew into the hole with my air compressor. Re installed the key and presto, everything worked with only the trailer battery. I always remove that battery disconnect key during winter storage so all kinds of dust, moisture, bugs, corrosion must have compromised the connection. I ordered a new unit as I’d imagine the old one is a weak link.
