I was testing the tow lights today ahead of as weekend trip. They mostly work ok.. a few touchy bulbs. When unplugging I noticed the connector was warm and the metal contact parts were almost hot. Testing took maybe 10 min. Background info: 1996 starcraft w tail lights and about 10 markers- all incandescent. We towed this trailer 6 hrs up into WI earlier this season with the mini van. No problems but I dont remember feeling the connector for warmth. TV= new toyota 4runner. First time plugging in a trailer. What do you all think? High amp draw from incandescent lights or high amp draw from a short/ bleed to ground of some kind?
