Powering up the Drive Controller
The KSI input is the primary control power for the drive controller. This originates from the keyswitch input
when the vehicle key is in the on position. The drive controller is also enabled/disabled by the interlock and
seat switch inputs. If either of these inputs is open-circuit, the drive controller is disabled. When closed, they
provide positive battery signals to the controller.
When the drive controller is active, it energizes the coil of the K4 relay, which in turn provides high-current
power to the controller for motor output.
