There is a auto shut down relay on the right fender that controls the fuel pump. It is the first relay from the front on the drivers side fender
not 100% sure. should be able to get a wiring diagram for your vehicle and trace wires. wiring diagram will show where relays and connections, fusible links, etc...... run the wire colors, from the fan motor to the relay....but a book does help lol...
have a diagram for identifying use of relays in the fuse box, will this help ?
Relays can be considered safe when used for remote switching. It only takes a small, low voltage current to activate a relay, which can then switch a high voltage, high current supply. There is no electrical connection between the coil and contacts. So switching dangerous voltages can be done at a distance, without anyone getting near the dangerous voltages.
In the black box on the right side under the hood. The fusible links, relays, fuses are there also.
The turn signal relays are in the engine fuseblock in the engine compartment under the hood. Diagram is on the lid of the fuseblock
fuel relays & fuel pressor
Inorder to achieve the impedance maching ....
Transistors, relays, and triacs.
Low voltage, either caused by low system voltage, or faulty wiring or connection.
THERE ARE 2 PRIMARY AREAS FOR RELAYS .THE FIRST SET IS BEHIND THE SMALL PANEL ON THE BOTTOM OF THE DASH ON THE DRIVER SIDE NEAR THE DOOR.WHEN YOU REMOVE THIS PANEL YOU WILL SEE YOUR PRIMARY FUSE PANEL AND 4 RELAYS.AND A CHART PRINTED ON THE INSIDE OF THE PANEL. UNDER THE HOOD IN FRONT OF THE BATTERY YOU FIND A BLACK BOX THEY ARE ALL RELAYS.AND TO THE RIGHT OF THE BATTERY ON INSIDE WALL OF THE FENDER THERE IS ANOTHER SMALLER BLACK BOX IT HAS 2 RELAYS AND FUSIBLE LINKS.NISSAN HAS DEVELOPED SYSTEMS INCLUDING MULTIPUL RELAYS AND FUSE FOR EACH ELECTRICAL FUNCTION...EXP...THERE ARE 4 PRIMARY RELAYS AND 2 FUSES AND A FUSIBLE LINK CONTROLING THE IGNITION ALONE......... ALL THE BEST........BUDDY MACK
Current transformers (CTs) are used to monitor the current (or lack of) in high-voltage systems, and their secondary outputs controls the behaviour of protection-system relays. The CTs (1) reduce the current to values that match the current ratings of the protective relays, and (2) electrically-isolate the relays from the high-voltage system.
Relays come in many different packages. There are SPST relays, SPDT, DPDT. Check the link below to see all the relay wiring diagrams.
