AL G1 Guide 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. 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.
