Definitions:

Voltage Drop Testing

A diagnostic method used to check the health of an electrical circuit, measuring the difference in voltage across the component or circuit while it is under load.

Ground Circuit

The negative or noninsulated side of a chassis, negative ground electrical circuit. When testing voltage drop on the ground circuit of a cranking system, total voltage drop should not exceed 0.2 volt in most 12-volt systems.

Voltage Loss

Voltage loss occurs when electrical energy is transformed into heat due to resistance, resulting in less voltage reaching the intended destination.

Voltage Loss

The reduction in voltage in an electrical circuit, typically due to resistance or impedance in the circuit components.
