Question:
Can i use the blue aux circuit to charge the battery on the pop up trailer?

Expert Reply:
Typically, the blue wire on a 6-way connector is used to carry the output voltage from the brake controller.
The 12-volt auxiliary feed, which usually feeds the center pin on the trailer connector can be used to maintain a fully charged battery, but will not have enough amperage to charge a dead battery.
