A vehicle high voltage system may include switches (e.g., IGBTs, contactors, relays, etc.), wires, a traction battery, electrical components with electrical properties and at least one controller. The at least one controller may be programmed to modulate a switch to provide a testing voltage for the electrical components, which is less than an operating voltage of the battery, and in response to a current flow associated with the testing voltage being less than a predetermined threshold, stop current flow between the battery and electrical components.
