Hi, sorry for starting yet another senors thread. I bought my new 28bhe last fall and didn't get to use it until this weekend. The fresh water sensors don't seem to work. The dealer is 1200kms south so I have to fix it myself. If it's the ground can I test that by adding a ground wire to the bottom wire(white wire) and go direct to the frame? I can't reach the other end of the current ground to see if it is that end of the connection.
Yeah, all the others are fine. Even the fresh water worked last fall on the drive home. Gonna try a ground with alligator clips tonight to see if it makes a diff.
Turned out the ring terminal on the ground was just squeezed between the frame and belly shield. They put a screw in but missed the ring. All fixed now.
Just out of curiosity, and logging it for future reference, were your sensors showing your tank full when empty, or empty when full prior to fixing your "anti-grounded" ground ring? lol
