  "textContent": "Systems and methods are described for monitoring a high voltage electrical system in a vehicle. An interface circuit is configured to provide isolation between a high voltage component of the vehicle and a control module. The interface circuit comprises a high voltage constant current source, a voltage threshold detector and an electrical isolation circuit. The high voltage constant current source is configured to receive an input at a first voltage from the high voltage component. The voltage threshold detector is configured to receive an output from the high voltage constant current source and to output a signal to indicate whether the voltage of the high voltage component is at, or below, a desired voltage. The electrical isolation circuit is configured to receive the output signal from the voltage threshold detector, decouple the output signal from the high voltage component and, in response to receiving the output signal from the voltage threshold detector, output a signal at a second voltage to the control module.",
