It is a single-pole, double-throw (SPDT) relay that is rated for 30 amps at 12 volts. The 6RA relay is available in a variety of configurations, including with and without a built-in diode. The 6RA relay is a popular choice for automotive applications because it is reliable, durable, and easy to use. It is also relatively inexpensive, making it a good value for the money. The 6RA relay is typically mounted in the engine bay or under the dash. It is connected to the battery, the starter motor, and the ignition switch. When the ignition switch is turned on, the relay energizes and sends power to the starter motor. This causes the starter motor to turn the engine over and start it. The 6RA relay can also be used to control other electrical loads, such as a fuel pump or an air conditioner. To do this, the relay would be wired in series with the load. When the relay is energized, it would send power to the load. The 6RA relay is a versatile and reliable component that can be used in a variety of automotive applications. It is easy to install and use, and it is a good value for the money. Here is a more detailed look at the 6RA relay wiring diagram:
