DIY - Relay EASY Step by Step Electrical Wiring + Fan Example - Very Simple!

[@JodBronson]

*WARNING NOTE:* This is a 12V DC RELAY in Video to make things simple for " Normal People " to understand. There are multiple voltages range of Relays, so BE AWARE WHEN USING OR BUYING FOR YOUR PROJECT.... From 3 VDC to 32 VDC, commonly used with most solid-state relays, makes it useful for most electronic circuits. The Control Circuit is the part of the relay that determines when the output component is energized or de-energized.

It's just the way I made the diagram. One should be on the On and the other should be Off. Basically.... Off to the Battery Negative (-) and On to the Relay.

I have dual fans installed in my 63 impala. Almost done with my build. What size fuse should I use in between my relay and positive battery post

Check the Rating(Wattage) of your FAN, you buy the fuse accordingly and a bit above that.

[@JodBronson]

+fhl1996 Maxwells la Bestia - By the way, removing the " Clutch Fan " and replaced with Electronic Fan is the BEST decision you have made for you and your Truck / Car. Here is why... A Clutch Fan is around 2-4 Horse Power (Depend on Trucks) under " normal " operations. But when " seized "...., it can be as high as 15HP or " Whatever " the speed you are driving. An Electronic Fan as an average is under 1HP and doesn't matter with the speed. BUT...., Clutch Fan during operation can be varied due to Vehicle Velocity. By removing the Clutch Fan, you are " Elevating " that " Velocity " from your Engine. This will " relieve " the Engine from working too hard and prolong your Engine Wear / Tear. At the same time, you save Gas, your Alternator and Water Pump and Steering Wheel Pump will work LESS..... This will help EVERYTHING work better and more efficient and BEST OF ALL.... Your Alternator will produce more Power which will need to " compensate " for your Electric Fan. #1- Your Car Cranks EASIER and less wear on your Starter too!

Hey jordan, i have a question. could i run a car radiator fan from a 220v outlet in my house? if this is possible please help me out and ill give you more details of the project. thanks a lot.

[@JodBronson]

Short answer = NO!

[@JodBronson]

You can if you use a Step-Down or an Inverter. Most/All Car Radiator Fans is 12V DC. You must step down the 220V AC to 12V DC. Also, the AMPS "must" match the Fan Ratings as well.

[@danyo5509]

Thermostat has two negative poles? And do you have to pick the size fuse amperage based on the fan, toggle switch, thermostat, and ignition? What poles determine the amperage needed for the right fuse?

[@JodBronson]

@Danyo - YES, the Thermostat " BOTH " Poles are Negative (Thermostat Disc act like an On/ Off Switch). YES, Thermostat + Toggle Switch + Fuse = Base on Fan Ratings. Ignition on Car is 12V DC, it only supply a " SMALL " amount of Electricity to turn Relay On / Off :).

Jordan Bronson I’m trying to do a accessory light with a rocker switch. Is a relay necessary if I just want to turn it on/off with the switch only? Also the rocker switch says 20amps 14vdc.

[@JodBronson]

@@danyo5509 - Check " ALL Accessory Lights Rating - Total ". If " ALL Total " of the Lights is under 20 Amps.... There is NO NEED for Relays, the Switch alone is all you need! NOTE: If you are running " Long Wires " with these Lights, then heavy Gauge Wires will be needed.

[@danyo5509]

Jordan Bronson I have some 14 gauge wire. But I’m wondering if the rocker switch is using 20 amps for that light or is 20amps the max input? Thanks

[@jeffreywin584]

Hi Jordan. How nice of you to respond! I have just installed an upgraded A/c system in my 1974 Bmw 2002. Components are in and I am trying to figure out my wiring to the new condenser fan up front. The old one had a thin wire coming from the cabin wiring inside the A/C faceplate where the vents are in front of the evaporator and branched off to power the compressor clutch as well under the hood.. There is a relay in there behind the faceplate which I assumed was for the fan inside of there blowing the cooled air out of the vents. But it seems so weird to me that there was no relay closer to the fan at the condenser up front, nice and close to the battery. I bought a 30 amp relay and inline fuse holder yesterday, thinking it would be the right way to go. The new fan in the front pulls up to 20 amps. Now I have to figure out the exact wiring. I have the 12 volt thin wire the switch inside, the ground from the old fan up front and then my new fan with two wires, issue for power and ground. Do I wish my father was still alive. He was an electrical engineer and would know this stuff cold. Well, I will do my best, voltmeter in hand. Thanks again! Scott

Good decriptive video. I am wondering why you need to have both pins 30 and 86 directly connected to the battery---Is this always the case with relays?

[@lexsoft3969]

Very good. I find that a textual explanation with a clear diagram/picture is better than a speech explanation at times. The idea of using thermostatic disc is excellent. My radiator fan turns on whenever the ignition switch is ON. But I have to check the existing circuit for radiator fan to see if I can modify it to enable addition of a thermostatic disc.

[@JodBronson]

+Lex Soft - I am glad it's useful to you :D. NOTE: Don't change anything.... Put a " Snap Disc " at the Radiator... Cut your " Negative Wire " and attached that to the Negative Wire, you will be all set :)))... Easily solved!

[@lexsoft3969]

+Jordan When you mention "Negative Wire", does it mean the wire which connects to the fan from the battery ? To be clear, you can explain it by writing a "textual diagram" here. For example : Battery Negative -> Snap Disc terminal 1 -[Snap Disc Body ]- Snap Disc terminal 2 -> Fan Negative There are 2 radiator fans on my car. It has one relay and 2 fusible links. Looking to your drawing, maybe it's better to connect one terminal of the snap disc to the battery negative terminal, and connect the other terminal of the snap disc to body ground, since relay terminal 85 is connected to ground. My version of "Textual diagram" : Battery Negative -> Snap Disc terminal 1 -[Snap Disc Body]- Snap Disc terminal 2 -> Body ground What do you think ?

[@JodBronson]

Leave everything you have now, don't make it complicate... CUT your Negative Wire ONLY !!! Like.... Battery--------- Snap Dics --------- Fan Negative.

[@JodBronson]

Pause at 2:38 in the Video. That is what you will have to do! NOTE: " Replace " the Switch with your Snap Disc :)

[@JodBronson]

+Lex Soft - By the way.... Use 2 (TWO) Snap Disc. One is for your Radiator and the other one is for your AC Compressor.

Putting everything together, also a 30 amp fuse ,you think is ok.?

[@JodBronson]

+fhl1996 Maxwells la Bestia -Anytime you deal with Electronics. You need to see the " device " that you are using. In this case it's a FAN..., you will need to find the Fan's Rating. From that Rating, your Fuse, Wire and EVERYTHING else must be above the rating in order to " prevent " Damages / Fire! EXAMPLE: Lets say you drink coffee out of a cup. If I give you a big straw, you will drink faster.... But if I give you a small straw..., you will drink slower. Now lets say, you only got 2 minutes to drink out of a straw... Which one would you choose Big or Small? I think you know the answer!

+ Jordan I found a high speed electric fan ,from a town car , for My 93 Bronco , I remove the mechanical fan ,and adapt the electric fan, but first Bought a thermostat control, were you can adjust the fan to turn on and off . I follow the instructions and work real good, but the positive wire gets real hot almost to melt the 30 amps fuse holder, now that I found your information on you tube is so easy to understand, my question is first, you think I can get the power from the ac switch, instead of the ignition? Second, can I keep the thermostat control .?when I don’t use the ac,? And a thermo disc is going to help the wires not to get too hot,. Thank you for your time, God Bless you.

[@JodBronson]

+fhl1996 Maxwells la Bestia - Your WIRE is the Problem... You need at least 10 Gauge Wire. If you go " Long Distant " you will need " Heavy Duty Wire ".

[@JodBronson]

+fhl1996 Maxwells la Bestia - Basically your Fan is drawing too much amperage, it's melting the wire :(((

[@JodBronson]

+fhl1996 Maxwells la Bestia - Add 2 Thermo Disc... Different Temp, SAME HOOK UP.... That way one is on the AC Condenser the other is on Radiator. They will be " Redundant " but will work efficiently :)))

[@JodBronson]

+fhl1996 Maxwells la Bestia - Buy 2 Disc.... Radiator is either 80(176F) / 85(185F) Celcius and for the AC Condenser, I would go 60(140F) Celsius.

+fhl1996 Maxwells la Bestia - NOTE: Pause the Video at 4:35 - Use #1 for Radiator. Use #2 for your AC Condenser...... That way it will be ALL automatically for you :).
