Power Door Lock Switch: Diagram Information and Instructions
Electricity
Electrical power flows from the power source to a load device and then back to the source of power. The electrical circuit should contain a device
to open or close the circuit, such as a switch or relay, and a protective device (in case of an overload), such as a circuit breaker or a fusible link.
Electrical circuits can be set up as series circuits, parallel circuits, or series/parallel circuits. The circuits in this vehicle are normally parallel
circuits.
Series Circuit
Series Circuit
In a series circuit, the electrical devices are connected to form one current path to and from the power source. In a series circuit the voltage is
shared equally by all the devices in the circuit.
Parallel Circuit
Parallel Circuit
A series/ parallel circuit consists of a single current path and a circuit with more than one current path to and from the power source. In a parallel
circuit the voltage is constant and equal for each current path.
Series/Parallel Circuit
Series/Parallel Circuit
A Series/Parallel circuit consists of a single current path and a circuit with more than one current path to and from the power source.
Cell References
CELL REFERENCES
General Motors vehicles often use "CELL" references in their electrical wiring diagrams. These references are used in the Original Equipment
Manual to refer to a section in the manual and not a specific diagram(s).
