Firstly, what defines a tractive system?
For our purposes, this system describes the equipment and wires which send energy from the high voltage (60V - 600V) system to the motor. The ultimate goal here is to generate traction, and it is important to note that it is connected to (but not composed of) the energy storage system. In practice, this means that it is inclusive of all high voltage after the accumulator isolation relay (AIR) coils are engaged.

Here is our schematic for the tractive system as pictured in the Electrical Systems form (ESF). You'll notice that some of the elements like the Motor Controller and Motor look a bit different than they do in the master schematic, which is because they were simplified. These components serve a wide array of purposes, but only a few connections are relevant to the operation of the tractive system.
Additionally, the only relevant portions of the accumulator and low voltage box are the entering and exiting wires. None of the internal components of either enclosure are included in the diagram.
Shown below are a few of the major components depicted in the schematic.
