Yes, sender is grounded. Everything is fine at the sender. The black wire at the guage might have a pink tracer. If what you say is correct, my wires are fine. I unplug the wires from the guage and it reads full. I connect the black/pink wire and it reads empty. However, I am a little confused. Should the brown wire read the resistance/ ohm from the sender? Wes Vanns post in tech reference seems to say that also. After all, doesn't the guage read resistance (brown wire)? With the tank full it should read 90 ohms; empty tank, 0 ohms. In your last post you said it should read zero?
