Hi all, just got a 2011 jayco 24rb tt and noticed the brakes were not working on the way home, I now have it unhooked and back next to house,
my question is how to check the brake system without moving it again,
the tv system is ok as it worked ok on my last tt. but I will check it again. the battery on the tt read 13.4 so I think it is good.

The trailer battery has nothing to do with it's brake system except in the unlikely event the trailer disconnects from the tow vehicle, causing the breakaway switch lanyard to pull the pin and apply full battery power directly to the trailer brakes. During normal towing your trailer brakes are powered by voltage provided by the brake controller mounted in the tow vehicle so obviously they won't work if the TV's brake controller isn't outputting the correct voltage on Pin 2 of your vehicle's Bargman connector. Have you measured for this correct voltage between Pin 2 (brake controller output) and Pin 1 (Ground)? :@
