4. a) Assume that the indicator lamp flashed yellow
in test a) above. Reset all connections to their
original positions. Then disconnect AR. Connect
a new loop wire to AR. Connect the other end of
this new loop wire somewhere at the centre of
the installation.
If the indicator lamp is green or flashing yellow,
then the break is somewhere in the wire between
the disconnected end to the point where the new
wire is connected (thick black line in the
illustration 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 or
flashes yellow.
Continue until only a very short section of the
wire remains which is the difference between a
flashing blue light and a solid green light.
b) If the indicator lamp flashed yellow in test 3b)
above, a similar test is carried out but with the
new loop wire connected to AL instead.
