En la terminal marcada con el numero 30 deberás alimentarla con carga positiva, esto la mantendrá preparada, una vez que se active tu relevador el contacto cambiara del contacto 87a al contacto 87 (que es donde tienes conectado tu dispositivo) y fluirá corriente a través de el para hacerlo funcionar. Terminal 85 and 86 are the coil terminals, which are used to activate the relay by providing a small amount of power to the coil. Connect the power source to pin 30 of the relay. As compared to a standard 4-pin SPST relay (with terminals 85, 86, 30, and 87), the 5-pin Bosch relay has an extra terminal 87a, which is powered only when the relay is not energized. This is the On position. -COM - This is the common terminal of the relay. The following procedure applies to the ASD and fuel pump relays. Pin 87 is connected to the device you want to control. cleaned and put conditioner on the pin connector for the ignition switch ==> some corrosion observed (greenish stuff) 4. 88. In a five-pin relay, the relay’s high amperage circuit consists of three terminals, 30, 87, and 87a. A 4 prong relay is commonly used in automotive applications to control electrical devices such as headlights, horns, and fans. In these, one terminal could test good and power the fuel pump relay and the injectors, but the other could be bad and not power the ECU. Aug 21, 2023 · Set the multimeter to DC voltage (20V), then measure the voltage across the COM (30) and NO (87) terminals. 87a can be used for many different things such as relay activation monitoring or connecting a separate May 15, 2012 · The main relay is a 5 prong relay with 2 terminal 87's. 990 (E55 AMG), 156. Grounding terminal 86 energizes the relay and closes the 30-87 power circuit. Dual Make SPST Relay. Figure 5 On the side of the relay will be a wiring diagram showing the function of the relay; the terminals correspond with the numbers located on the bottom of the relay. rk io xz gg xl op ir he pd zd
