The technology disclosed herein enables a detector of a high voltage interlock loop to determine connectivity of high voltage connectors on an individual basis. In a particular example, an apparatus includes a loop current source configured to transmit a loop current for the high voltage interlock loop. The apparatus also includes a first-jumper current source connected to the high voltage interlock loop in parallel with a first jumper of a first high voltage connector. The apparatus further includes a second-jumper current source connected to the high voltage interlock loop after the first-jumper current source and in parallel with a second jumper of a second high voltage connector. Also, the apparatus includes a detector configured to determine connectivity of the two high voltage connectors based on whether the loop current, the first jumper current, or the second jumper current is received by the detector.
