Turn and brake are combined on the coach. They work properly.
The brake and turn functions get combined in the multi-function (turn signal) switch. Since the ones on the coach are fine, the only thing I can think of is that the circuit for the trailer connector is separate from the circuit for the coach lights.
Dolly is fairly new. LED lights. Right side lights up as expected when I use the turn signal or 4-ways. Checked at the connector and no voltage when brakes applied on that pin.
Will be seeing my favorite Ford man on Saturday so I guess I will have to ask him. Was hoping that someone here knew for sure.
