The grommet is the white bit you can see in this photo. One end of the wire sits outside it contacting the outer metal sleeve, the other end runs inside it to contact the hollow metal pin in the centre. The metal pin is quite loose so gets pushed in by the battery, squashing the white rubber. If you get me.
