A method of monitoring for circumvention of an ignition interlock system is described herein including detecting an electrical parameter associated with an electrical power state of a vehicle electrical system in a vehicle comprising an ignition interlock device that includes at least a relay device and a controller device electrically interconnected within the vehicle electrical system, measuring a rate of degradation associated with the electrical parameter of the vehicle electrical system, and comparing the electrical parameter to a threshold condition. The method further includes comparing the rate of degradation of the electrical parameter to a threshold rate. Depending on the rate of degradation, a violation state may be generated, a violation state may be reversed, a violation state may be maintained, a log entry may be generated, or more than one of these may occur.
