above: Put AL and G1 back in their original
positions. Then switch AR and G1. If indicator lamp
now is lit with a solid green light then disconnect AL
and connect a new boundary wire to AL. Connect
the other end of this new wire at the middle of the
suspected wire section. Follow the same approach
as in 3 a) and 3b) above.
5. When the break is found, the damaged section must
be replaced with a new wire. Always use original
couplers.
