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 L 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 L and Guide back to
their original positions. Then disconnect R. Connect
a new loop wire to R. Connect the other end of this
new loop wire at the middle of the suspected wire
section.
If the indicator lamp now is green, then the break is
somewhere in the wire between the disconnected
end to the point where the new wire is connected
(thick black line below). In that case, move the
connection for the new wire closer to the
disconnected end (roughly at the middle of the
suspected wire section) and check again if the
indicator lamp is green.
Continue until only a very short section of the wire
remains which is the difference between a solid
green light and a flashing blue light. Then follow
instruction in step 5 below.
4. If indicator lamp still flashes blue in step 3
above: Put L and Guide back in their original
positions. Then switch R and Guide. If indicator lamp
now is lit with a solid green light then disconnect L
