- Diagnostic Cables
- Zero Sevcon programming cables are part #86-06747 connected as follows:
- Pin 1 is "Key Switch In": power for the logic circuits.
- Pin 2 is linked to pin 24 via 120Ω resistor to tell the Sevcon that it's at the CANBus termination.
- Pin 13 is "CAN High".
- Pin 27 is "CAN Low" in the Sevcon manual (pin 24 also is, unless used for termination signal).
