Towing without a battery
So a co-worker has a TT and wants to move a short distance but does not have his battery close by. He wants to know if he'll still have break lights, running lights etc if only hooked to the vehicles ...

of course if he has an accident there will be issues for towing something requiring brakes with no brake hookup. it is not for the "emergency" brakes, it is for the trailer brakes to assist the TV in stopping.

Not true, the brakes get their power from a different wire. The trailer brake controller provides that voltage directly to the brakes. To operate as you have stated would take a variable relay, which is not part of the equation.
The only thing the battery is for is the emergency brakes if the trailer separates from the truck.
If you look at the wiring the emergency brake-away switch has two wires. One goes to the 12V + side of the battery (actually a distribution point in the front of the trailer) and the other taps into the brake system. Unless the emergency brakes are activated they are separate systems.
I stand corrected. what I should have said is if your have a break away and smash things up, your lack of the battery and brakes will be an issue.
