okay so when i got my premier 31bhpr the water tanks were full so i didn't notice the sensor didn't work. i finally got around to looking into the problem. yeah it is under warranty but don't feel like losing my trailer for a month for an easy fix. there were actually two problems. a leak when i filled my water tank and the sensor would read full with any amount of water in the tank and then read empty when it was bone dry.
so i removed five self tapping screws from the under belly on the port side of my trailer.
this i what it looked like. if you notice the three bolts on the left, i had already removed the wires before i realized this info might help you guys.

the leak was coming from the fill tube. a few turns of a screw and that was all fixed up. weird that it just loosened itself after a few trips, but better than a break.

this is the correct position of the wires. all nuts were loose when i got to them, and the red one was on bottom and the the green on was on top. that is why it read full when i put any amount of water in there.

im not sure what these wires are for, but they were just laying there.
anyway who wants to drop off their trailer for a month and have to fight with keystone about a warranty? i am stoked that they were easy fixes, and now i know what that looks like in there.
