Wiring Diagram Relay 85 And 86 Use

Terminal 85 connect to a suitable earthing point on the vehicle chassis.

Wiring diagram relay 85 and 86 use. This circuit diagram of an inactive spdt relay with no power applied to pins 85 and 86 ground and 12 volt positive. Terminal 86 from relay 1 terminal 86. Looking at the diagram we see the pinout of a typical 12v relay. 85 and 86 are the coil pins while 30 87 and 87a are the contact pins.

Terminal 86 from one side of momentary switch. 87 and 87a are the two contacts to which 30 will connect. The left side is the pin out of the point is sticking out from at the bottom and the the right side is showing a schematic representation of the relay circuitry. Numbers of a relay.

This diagram shows an active spdt relay with power applied to pins 85 and 86. Note that each pin is numbered. Pin 30 common and pin 87a normally closed are connected. Wire colours compressor red pin 30 red battery pin 87 yellow compressor pin 86 yellow binary switch pin 85 black chassis ground note pins 30 and 87 are the power switch while pins 85 and 86 are the relay trigger.

30 and 87 create the switch to your lights. If the coil is not activated 30 will always be connected to 87a. How to wire your light using a relay the relay will have 4 points on it marked 30 87 85 and 86. 4 pin relays use 2 pins 85 86 to control the coil and 2 pins 30 87 which switch power on a single circuit.

Terminal 87 to terminal 86 and relay 2 terminal 86.
