Acura is known for offering an exhilarating driving experience. Its vehicles are packed with technology, and costs thousands of dollars lesser than its European competitors. Quality Acura parts play a huge role in sustaining this excellent reputation. One example of these quality parts is the Acura relay.

Invented in 1835 by Joseph Henry, the relay is an electrical switch that opens and closes through another electrical circuit. It was, earlier, operated by an electromagnet to open or close one or more contact sets. Acting as an electrical amplifier for an Acura vehicle, the Acura relay controls an output circuit of higher power than the input circuit. A typical Acura relay works for several different applications. First, it controls high-voltage with a low-voltage signal and a high-current with a low-current circuit. Relays also conserve energy, perform logic and time-delay functions, and isolate the controlling circuit from the controlled one when the two are at different potentials.

Connector failure is the most common cause of Acura relay-related electronic failures. Such problem occurs when the current flow through the relay heats up the relay, which in turn, heats up the connector. As a result, the connector looses its grip from the relay and begins to overheat. Eventually, the plastic around the connector will melt, leading to the Acura relay's failure.

One example of an Acura relay is the fuel pump relay. By principle, a hot relay is a bad relay. In the first place, drawing high amount of current should not result to a hot relay. A relay failure in this situation can be attributed to different factors such as a cold solder joint, bad crimp joint, and bad relay contacts. A burnt smell and an engine that fails to start are the usual symptoms of a faulty fuel pump relay. An Acura relay failure may either be fixable or non-fixable so it is highly recommended to have the relays checked regularly to avoid irreparable damage.
