How a 5 Pin Relay Works

[vinceweaver]

Thank you! After trying several other wiring diagrams that didn't work, this actually told me what each of the relay leads do, and I figured the wiring out myself.

[Aym_Riha]

finally someone explaining in detail what that mysterious 5th pin is for. Thanks a lot.

I understand relays but I don't work on auto relay circuits very often and this is a very clear explanation. Thank you.

[muhametkondi]

VERY SIMPLE, VERY CLEAR AND VERY PRACTICAL. THANK YOU

[emanence]

thanks for making this video, no one really explains or understand what 87a on a five pin relay does. thanks again.

[JacquesButcher]

Excellent video. Made it so easy to understand.

[ivanmonteiroc]

Very, very good! Now I understand it properly, thank you very much!

[CodecFace]

Great video! Best explanation/tutorial I've seen. Thanks!

[rohitshrivastava]

Excellent explanation. Very good work. Very useful for beginners..

OMFG I'VE BEEN SEARCHING FOR AES FOR SOMETHING LIKE THIS THANK YOU YOU ARE MY GOD

Nice, also testing is easy for normally closed 30 and 87A should read 0 ohms with no power applied, and with power applied as shown in the 30 and 87 should read 0 ohms indicating the circuit is closed

Power applied to 85 and 86 makes 30 to 87 close, and no power opens that circuit and closes 30 to 87a making it normally closeed with no power

Thanks for the vid

Hello sir, i have very low knowledge on electrical. I install DRL into my car, but when aircond is operate or radiator fan is start spinning, the DRL become a bit dimming. Is this relay can maintain enough power to DRL when aircond is operated, or i need other device?

[MyBluetti]

I'm a little confused... maybe this doesn't fit my application and that is what is confusing me. However I have a need for a single device to have two separate power sources. When the switch is off I want one power source to feed the device. When the switch is enabled I want the power source to be from the other feed.

My application is that one power source is direct from the battery to a LED light bar. The second power source is LED flasher unit. Therefore I want the default power to be stable power for constant light.... and when the switch is enabled the LED flasher to control the power.

Is this possible with this 5-pin relay?

Thanks for the help. Good to know information! Thumbs Up!

Can 87 and 87a go to the same bulb? I like my turn signal repeaters to stay on the same time as the park light and flash when you flick the switch for turn signal/hazard lights.

sweet video. Is the 30 terminal always the common power terminal?

[wagonkit]

so 86 and 30 go straight to the battery? Or should one or both be fused? My harness seems so backwards to this as far as coloring... blue is 30, 85 says to go to ground, 86 is white and says to go to switch, 87a is red and says nothing, 87 is yellow and says to go to light... worse case if i hook it up wrong...? Burn the relay?

very helpful, thank you very much

[JustaCuriousity]

hi, i wonder why my relay doesnt have 87a but 87. so it only has 85 86 87 87 30. when i connected wire like illustration, i switched on, used multitester testing 30 and both 87, those are all connected. anything wrong? thanks.

yea, very god bro . now I understand
