Next, you will need to measure the current and voltage present at the truck's umbilical when brakes are activated. That will inform as to the operation of the brake controller and connectivity to the trailer's brake circuit. Or, more accurately, measure when the umbilical is connected.
Thanks for promoting the use of a meter. It should be in the tool box of all TT owners.
I wouldn't go anywhere without that meter and a jumper wire
with that little jumper wire you can easily check the lights too. I have been in campgrounds where some had their running lights on all night(not sure why but.....)
I will be checking the truck's output to the trailer, I will post that too
