What is another term for parasitic draw in electrical diagnostics?

Parasitic draw refers to the electrical current that continues to flow when a vehicle is turned off, which can lead to battery drain over time. The term "current leakage" aptly describes this phenomenon since it indicates that there is an unintended flow of current that is not associated with the normal operation of the vehicle's electrical systems when the engine is off. Detecting parasitic draw is important in diagnosing battery drain issues, as it can point to malfunctioning components or systems that fail to shut down properly.

The other options do not accurately represent this specific issue. Voltage spikes generally refer to sudden increases in electrical potential that can cause damage rather than an ongoing current draw. A short circuit implies a direct connection between the positive and negative terminals of a circuit, which results in excessive current flow and can lead to overheating. Overcharging refers to a condition where the battery receives more voltage than it can handle, which is not related to draw when the vehicle is off. Overall, "current leakage" is the most suitable term for describing parasitic draw in electrical diagnostics.
