To further this, what is happening is the variable resistor is open
somewhere in the middle.
This sending unit has lost its reference and is now just a solid piece of
wire with no variable resistance above the break that is always at full
battery potential. That is why it is showing full most of the way.
The same goes for the lower portion of resistance, it is just another solid
connection all the way from the break to ground. Thus, the reason for the
empty reading.
Send it back to your supplier. It's not worth trying to fix and it also
voids any warranty.
