Hi guys. I have an odd issue this year after several years of successful towing without any lighting issues. This season when I hooked up the boat trailer my running lights didn't work. Always worked in the past and I haven't changed anything. I use the same Curt hard wired adapter as usual. I noticed that the orange and red wire on our towing plug that I draw power from to the adapter shows .05 volts with headlights on and 0 when off. The vehicle tail lights work fine. I checked the towing fuse (22) and it was fine. Any ideas? Thanks in advance.
