Definitions:

Ground Circuit

An electrical circuit that uses the earth as a part of its conductive path, enhancing safety by preventing electric shock.

Insulated Circuit

The positive side of a chassis, negative ground electrical circuit. When testing voltage drop on the insulated circuit of a cranking system, total voltage drop should not exceed 0.5 volt in most 12-volt systems.

Voltage Drop Testing

A diagnostic method to measure the voltage loss in a circuit under load, identifying potential issues within the electrical system.

Cranking Circuit

The chassis electrical circuit that supplies the high-current load required to crank an engine. Also known as starting circuit.
