Electric Brake Problem

Just returned from trip, stopped over last night and left truck hooked up to fiver. I also left 7 pin plugged in and then hooked up to campground electric. When I left this morning, the electric brakes were locked up. Did leaving it plugged in to truck cause a problem? I attempted to back off on juice to brake controller but it did not seem to help, had to stop every 5 miles or so to let brakes on camper cool off, if I continued it would cause smoke coming off brakes. I was able to get home OK, but any suggestions what to check first. Camper is Brookstone 345SA, using Tekonsha Primus brake controller. Ford F-250 Super Duty

    Are the brakes locked up when the 7 pin is unplugged? If so, it is the breakaway brake switch. If only driving a short distance home, I would have taped off the brake pin on the 7 pin, leaving lights enabled but not brakes.

    EDIT. If it is the breakaway switch, taping off the brake pin on the 7 pin would do nothing. In that case, you'd have to dissconnect the trailer battery and the 12 VDC pin on the 7 pin.
