Back into the detection wiring again...

Now that school holidays have finished its back into the wiring of the blocks into the remaining two (2) BDL168's.  The next section is the Rutherford to Manheim Junction section, this will use two of the four (4) blocks and eight (8) sensors.

The configuration is not really pretty but it works and makes problem solving much easier if required.  The labelling is quite time consuming but again makes identifying the individual blocks easier.

Each zone wiring block is marked so that is identifiable from the other wiring under the layout.  The red (thicker) wires are the block power feeds from the BDL, and the white (with red stripe) are the corresponding track feeder.  The plain white wire is actually the black wire and common for the layout.

Keeping everything in order and labelled will save time in the future if you ever need to find faults in the detection wiring, it is also mind numbing and quite boring at times too.  Checking each block when connected is essential when working with so many wires and feeders, already I have picked up un-isolated block boundaries that required insulated track joiners to be installed.

Two more zones (8 blocks) to go and onto the last BDL168...
