3. Switch the connections between the guide wire
and the boundary wire in the charging station.
Start by switching connection AL and G1. Some
models have additional guide wires . The same
procedure can be followed for them.
If the indicator lamp is lit with a solid green light,
then the break is somewhere on the boundary wire
between AL and the point where the guide wire is
connected to the boundary wire (thick black line in
the illustration).

To rectify the fault you will need boundary wire,
connector(s) and coupler(s):
a) If the suspected boundary wire is short then it
is easiest to exchange all of the boundary wire
between AL and the point where the guide wire is
connected to the boundary wire (thick black line).
b) If the suspected boundary wire is long (thick
black line) then do as follows: Put AL and G1
back to their original positions. Then disconnect
AR. Connect a new loop wire to AR. Connect the
other end of this new loop wire at the middle of the
suspected wire section.
