[urq] Fuel gauge reads 3/4 when tank full

[Frank de Kat]

The 'braided wire' is the flexible connection between the stationary  
frame of the sender, and the moving slider that wipes the resistance  
element of the sender as the float arm moves.

Usually if the braid  breaks (so totally open circuit), gauge will  
just read totally empty, and not work at all.
It can be an adventure to solder that braid too, as it's usually all  
crusty, and ready to further brake apart..
