So I've been playing around with the wiring on the TV all summer (on and off) and am at a loss. When we took off recently for a week long trip, the Brakes/LT/Running Lights worked however the RT would not. I assumed it was corrosion from sitting over the winter on my TV as the dust cap had disappeared at some point. While camping, I decided to simply cut & replace the 4Pin connector on the TV. Doing so resulted in a solid RT signal. (All results are based on the 4pin tester) As I need to relocate my trailer this weekend, I decided to go out and take another look. Upon first attempt, the Brakes/LT/Running lights worked with the exception of the RT. I decided to give the ground a cleanup and reattach to see if that was perhaps what was preventing the RT from working. Since doing so, I'm only getting a solid RT. I checked the RT green wire and didn't notice any physical damage to the wire and checked all connections to ensure nothing came lose. Does the solid RT represent an overload? 2012 Dodge Grand Caravan using a Curt Wiring Harness (worked fine last season) Hopefully this is everything needed but please feel free to let me know if more information is needed. Thanks in advance!
