IGURE 12.1B SHORT BETWEEN RING AND GROUND
A Cross or Battery Cross is when TIP or RING is shorted (typically by water or moisture) to a lead that
contains CO voltage. This is typically at the point where there is a faulty splice and moisture can easily enter
into the splice thus completing a current path.
