I have a 2020 Jayco, Eagle 280- rsok trailer. Discovered that the right rear signal light (and brake light) wasn't working. Checked all 7 pin connections and eventually got my volt meter out, disconnected the brown wire at the trailer and found that the signal from my truck was getting through to the trailer. If I reconnect the brown wire (right signal wire) to the trailer the signal drops right off. Thought it might be a short somewhere inside the trailer. Inside my front storage compartment there is a battery disconnect switch attached to a panel. i opened it and found an interesting Flasher control module made by American Technology Components (pic attached). Anyone had experience with these modules?
