If no joy, your multi-meter search starts again at the terminals where the 7-pin cord is attached on the trailer. (on a 5er under by the kingpin, not sure where with a TT)
Sometimes the 7-pin positive on the trailer is spliced into another positive such as for the jacks and it is fused.
Of course you do this with the truck running so you can see the voltage is 13 or 14 something and not 12.x battery voltage.
Thanks for this. Looked in junction box under kingpin. No fuses there. I will try cleaning the terminals and checking grounds and see what that gets me.
