Power cabling transmits full traction power from the battery to the controller and then to the motor.

The cables are very thick, armored, and are covered in an orange mesh wrap for abrasion resistance and to indicate the danger involved if the cables are damaged.

Battery to Controller

• B+ (positive) and B- (negative) cabling runs in the power harness from the back of the monolith or long brick pack to the B+ and B- terminals on the motor controller.

  The position of the routing from the back of the battery varies by pack geometry:

  • 3- or 4-brick monoliths will have a doghouse on top but the main power coupling will be lower on the rear face.
  • Longbrick packs reside in the forward half of the monolith area of the frame with the doghouse on top. The power coupling seems to run along that top face of the compartment.

  The cables enter the central area of the frame and rise forward of the board mounting plate to emerge in front of the controller and run rear towards the lugs.

• Power Tank cabling runs from the doghouse on that brick to the same B+ and B- terminals on the motor controller.

  The cabling needs to route under the frame arch that supports the tank plastics and seat, typically under the right corner.

  The cabling then extends back under the Y-shaped subframe piece to the controller terminals.

  Power tank cabling lugs should be stacked above the main pack's lugs on the motor controller terminals.

Controller to Motor

M1, M2, and M3 phase cabling runs from the corresponding terminals on the motor controller.

The cables run forward from the phase terminals, below the Y-shaped subframe piece and then down the right inside of the vertical frame stanchion to the motor, behind the board mounting plate.

The cables are really affixed to the motor, so it's more accurate to say they run up from the motor through this area of the frame and then emerge and run back to the controller.
