How Electrical Connectors Work

Electrical connectors are a vital part of every vehicle on the road today. Electrical or wire connectors vary from a single connector to many wires depending on the application. The exact type of connector used on the vehicle will depend on the duty of the connector. For example, wire and connectors that carry reduced amps tend to be small, while those connectors that are handling heavy loads tend to be much larger. Connectors can snap together, slide together, and simply clip together; there are numerous types of connectors available. The range of options available is dramatic.

 All power accessory systems use connectors for example: radio, antenna, power window and even the alternator all use various forms of connectors. Most of the electrical connectors are designed and constructed from plastic with small metal components inside which transfer electrical power from one wire to another.

Common Problems and Solutions
The most common problem that can occur with a connector is a short circuit. This condition occurs when a wire close to the connector breaks or high resistance is present inside the connector itself. It is also possible for a connector to overheat and melt, this occurs when high amperage or resistance is present. If a connector within your vehicle has melted, turn the key off, disconnect the battery, repair or replace the connector as needed and recheck system.

One problem that is quite common with connectors is the safety clip that holds connectors together can break. There might be some circumstances when electrical tape is needed to hold the connectors together. Determining which solution is best for your situation and on how tightly the connector fits together.
Another common problem is when a connectors comes loose. This is one of the easiest problems to correct because it just involves pressing the connectors back together. Carefully pressing the ends together should allow the connector to snap into place.
Maintenance
Common maintenance suggests inspecting electrical connectors that are visible. Broken connectors are not common but possible, especially in older vehicles due to aging plastic the connector is made from. Connectors that are inspected can spare much aggravation and prevent malfunctions of equipment in the vehicle.
