Basic Relay diagram - IOW what goes where

[stephmc111]

. 87A is a second output on the relay, example, remember those old car and when buddy put the marker lights on, there was 2 amber lights on the front of the car and thay flash back and fourth, thats what the 5pin is for, im working on i light system for my bicycle, its on my channel. and i got two 40amp relays from TheSource, 5 pin. 12v basicly the five pin is a "two way" relay. hope this helps thumbs up if it does

[chivito1981]

mas claro ni el agua thanks ....

[ErikMartinez454]

ok so whats a hho cell???

give me an example

[kaisanever71]

Thanks, very useful :)

[haniffjamil]

this question is actually apart from relay system..its about the hho system...i wanna ask that where does the negative terminal of the hho connected to?



[Jx1x3]

So the 87 would go to an actuator motor ...

[Jx1x3]

What's an hho cell

[aburani1]

what is the best way to test the main relay in diesel truck because the truck did not start cranking only

[kopynd1]

thanks for explanation

[ELCHACHALAKO]

THANKS FOR THE ANSWER,,,just to make sure IM ON TRACK GUYS

[babyhulk510]

I tried this setup for car audio and it did not work unfortunately. Using a basic 30A relay from Radio Shack here is the setup that I found online that eventually got my amp working:

85 = Remote in (from car)

86 = Ground

87 = Battery

30 = Remote out (to amp)

[ELCHACHALAKO]

WHAT " HHo" cell means in the circuit? any body please

[alfa69er]

@ELCHACHALAKO

The HHo he is referring to is a hydrogen producing cell. It is commonly used when people want to obtain better gas mileage in their vehicle. Nevermind the HHo part its basically just the main output for the relay.

[ZRace67]

Thanks a lot for the helpful info. Great video.

[1uneek]

what is the switch going to the ignition used for? I took that switch out of my 66 impala without knowing what it was for. Did I make a mistake? Im just learning about relays because this car has one but no power. Im not sure what its for. The black wire is lose. Any suggestions? Thanks.

[inchyapperfanders]

fucking useless mate

[StructuredDRIVING]

87 x 2 outlets = 2 x power outlets from relay,FOR CONNECTING ,for example 2 X SPOTLIGHTS.

[moneyleaker]

87A is normally closed, whereas 87 is normally open. Engaging the switch will open 87A and close 87.

[dodgemaniace]

the relay with 5 connectors the extra connection is 87 A and always has power were 87 is the controlled by the relay

[bunnyz696]

I bought a wolo horn for my vehicle, i installed one on my jeep with no relay. but with the one i got i decided to have a switch for it which has a relay with it. now what sort of fuse can i use and where can i find it? thanks

[civicrocker]

To answer the question in the video, the fifth connector on a relay is just another output in parallel to 87 that would go to the HHO system. it is located in the center of all the other connectors. I am talking about aftermarket relays as each auto manufacture has there own design and pinout.

[01jordanfirst]

could i use any relay to make a few LEDs flash?

[RICKYRANKS]

Perfect demonstrations man because of you I saved my self from ordering a hid relay kit . I cant begin to thank you ....

[shayvanchris]

yeah right.

[man13preet]

there should be a protective diode between 30 and 85...other wise you will DAMNage it!

[domyaska]

THANKS

[qwertyma733d]

my relay have 5pins ....nd im confused wht goes where ..:S........the model of the relay is SRD-05VDC-SLC

[SKEEZIN08]

i love relays...i wired the relays so that when my car has been remmote started the radio stays off and doesnt come on and attract more attention to my car my system is pretty loud... also not mentioned in this video is that you dont have to hook 30 to 12volts you can hook 87 to 12volts and 87 to what ever it is your trying to send 12volts im going to try and make a video of different ways to use relays.

[ponchodoc]

This guy has got to be from UTI,what magical process in the relay makes it send current to the consumer(HHO cell)Where is the coil that pulls the switch contacts closed in the relay?Is there a clamping diode?AAAHHHHH the smell of a UTI education reeks in my nostrils over the internet. hahahaha

[tubeyouabc1]

Very nice video, but your explanation will not make sense until you provide an actual schematic or wire diagram representation of relay contact points.

[dosteddaram]

one of the best examples of use of that

[neckly]

oh dats nice i get it now... thanks

[neckly]

it was a really good video i just didnt get HHO? wut is dat?

[pavko6]

its just about a molecule like water (or is water) in a mechanism for an engine to run on this molecule, separating the Oxygen and Hydrogen, using hydrogen as fuel.

[limpopoace]

Hi there,

Thanks for all the advice and tips build my HHO gen and system based on your videos.

Keep going mate!!!!

[moonielo]

hey, do know a guy name Greg who does the superstorm cells? whatever happened to him, all his videos disappeared.. latest vid i saw him doing was something about making easy money online.. did he get booked or something? weird..

[hercprsound]

Whats the HHO?

[troubledtrouabdour]

I'm having problems finding a relay, everywhere I've gone they try to give me a fusible link. Do you know where I would be able to pick one up and how much?

[water2gashawaii]

The middle post is on when 87 is off. When the switch or power energizes the relay, the contacts move and 87 turns on, the middle connector then goes off. This is the difference between and SPST and a DPDT switch. Single Pole Single Throw, and Double Pole, Double Throw.

[bowtau]

this came in handy today with my relay and amp gauge install thanks again for sharing.

[johnnybraun77]

The fourth post (87) is "normally open" and the fifth post (87A) is "normally closed". Meaning that 87 will be "off" until you energize the coil (85 and 86 posts) and 87A will always be "on" until you energize the coil.

[bowtau]

2 words Great Info!

[whey20010]

does 86 have to go to a switch id like to have it jus to the ignition that way my hho system will just come on correctly

[alandxp]

excelllant explanation and good diagram

[RichardEGagne]

The 5th pin on the relay is to go to a second power accesory

[chavoya123]

the relay is 20, 30, or 40 amps? and the fuse is 20, 30 or 40 amos? the switch is necesary?

i am making a hho generator for hidrogen to the truck, and this is very interesting, easy to follow....the conections...

thanks

chavoya123

[milkman16]

very helpful man. I'm such a visual learner and this really helped big time. Thanks!!

[milkman16]

wow this really helped. I'm such a visual learner and boy did this help. Anyway you could explain the purpose of the relay? I know it converts a small circuit into a big one but i just don't really understand that I guess..

[titan2654]

very helpfull man thanks

[DannyBoyPT]

excelente dude! This help me a lot.. Nice work. thanks :)

[thebiggerpicture718]

cool diagram. what is HHO? I do car audio applications. We use 5 pin relays all the time.

[HHOFreedomCell]

Check out Relay 101 From:thebiggerpicture718

Sry left out the 718

[BigFireDave]

Ran out of characters. the terminals are usually called 87 and 87a a being the normally closed. Polarity is not a problem on 87, 87a to 30. SOMETIMES a relay has a built in anti surge diode on the activating coil to protect computers and solid state devices so polarity IS essential on them. So 87(a) or 30 can be the hot lead, its a mechanical switch and it makes no difference. I see computer input circuits that are "backward" from normal because the computer is looking for a ground input.

[BigFireDave]

The relays with the 5th connector is like a single pole double pole switch. The other terminal is a normally closed position and when activated will shut off when the other one turns on. They are very handy if you want power sources to a load from two different power sources or if you want power applied to one load and switched to a second load when activated. OR if you want something on all the time and shut off when activated (usually safety circuits)the relay is just a mechanical switch

[inspectorgadget3]

Steve;

I have a combo EFIE and PWM each has its own power supply. I understand the routing for the PWM side, But I plan to draw power for the EFIE from the ignition switch, Do I need a fuse in this power line to protect the EFIE.

[AlmostHydrogen]

not sure about that - to be safe I would say yes (I mean it couldnt hurt right?). However you might want to talk to a mechanic and see what he/she says.

I'm not a mechanic so take what I say with a grain of salt.

;)

[chiconian49]

@inspectorgadget3 So easy! I found the exact relay at Kragens.

[lustatus]

This diagram is wrong...notice that 87 should be connect to the battery and 30(amps) should be connect to the HHO...after that, every thing else is looking good.

[AlmostHydrogen]

Ummm... then the other sites where I got this info is wrong too.

If you have some support documents to show this is wrong, feel free to post them.

BTW is it possible that there is more than one way to skin a cat (or use a relay)?

[oobuc5]

@lustatus no its not

[oobuc5]

@lustatus test

[cribcat1]

danburford58 might be a car stereo installer and it is always good to have a ground to the battery through a wire(-) because a bad ground can cause an unstable stereo system or PWM malfunction with the high currents involved. The "ground" metal in your car may not always be grounded well. You can burn wiring... that's my analogy but I don't know his intended meaning.

[AlmostHydrogen]

ah... I see.

Besides if you hook up your cell negative to the vehicle chassis wouldnt it mess up the readings on an amp gauge? or possibly effect other vehicle components?

Like I said, I'm not that smart, but it seems it would.

[danburford58]

not really, just as long as you had it in line the amp meter would work okay, most of the cars wiring is to ground, except high current draws like, inverters, hydroxy gens, pwm etc.

[cribcat1]

relays are electromagnetic switches. think of an electromagnet attached to a light switch. when energized moves contacts usually in pairs but not exclusively.

[danburford58]

You must be sick of my comments by now, but you have a large following and there is a lot of wrong info out there, i just want to make sure that you get and give the right info. think about the travel of the ground current on your chassis? when you by a inverter for your car, the instructions and wiring comes with wires to connect to both terminals of the battery, not the ground of the chassis, this is because the inverter needs a lot of power, so does your hydroxy unit.

[AlmostHydrogen]

I dont get sick, but if its wrong make a correction w/ an easy to understand explanation.

Maybe its just me, but sometimes u go onto other topics that are not related to my situation.

For example, I have no clue why I would need an inverter nor do I know how to install one. IOW u reply w/ examples I have no knowledge of, so it really does me no good (just being honest).

U gotta remember I am not the sharpest knife in the drawer; so explain it like I'm a 7 yr old & stay on point plz.

:)

[danburford58]

Sorry, after your reply i realized that in my haste, i assumed that you connected the neg wire from the hydroxy unit, to the ground chassis of your vechile, which is not the case, My apology again.

[AlmostHydrogen]

no problem Dan, its all good.

:)

[FluxCapacitor2008]

I dont Know If this helps.

Keep up the good work

[AlmostHydrogen]

It does & thanks.

[FluxCapacitor2008]

Battery power runs to a switch then to the + side of the relay coil and the -- side of the relay coil runs to the ground. The switch turns the relay coil on and off. The relay can have a normally open contact N/O),normally closed contact (N/C) or both.

So if you run the battery power to the relay N/O contact and then to your cell the switch will turn the relay on and off and the relay will turn the cell on and off.You use a relay instead of a switch because the relay can handle higher amps

[AlmostHydrogen]

N/O... N/C... or both?

Just when I thot I knew something, more stuff comes along.

Thanks for the info, I appreciate it.

[excell4God]

Always good to know how these things work.

Thanks.

[AlmostHydrogen]

Yea when people ask me questions, it forces me to study & find out = good stuff.

[mowerman54]

There are many types of relays. I have relays on my outside wood furnace that when activated turn on three different devices at one time. Could be used for turning on something like O the strobe lights in your bubbler, just kidding, but a multiple relay could be used for also turning on a circulation pump at the same time as the bubbler.

[AlmostHydrogen]

Now that is pretty cool - thanks.

[InstallGuys]

YES! Exactly what I was talking about on the last vid. For some reason in your last install vid I thought you had hooked the switch up between the positve terminal on the battery and the #30 on the relay, which could kill the switch. Hey, I have found the "Add-a-Circuit" at my local Auto Parts to be GREAT! They plug right into your fuse box, and have a wire lead that you can wire to the switch then the #86. Simply plug the existing 10A fuse back into it, and WALLAH! Use ACCESSORY line & fuse

[AlmostHydrogen]

This is the reason I leave comments = I get to learn more stuff.

The add a circuit looks like it would be a useful tool as well.

:)

[lutherp40]

5th contact is the back making contact.

this is for energizing something when the relay is dropped out.

[kennym782]

Sent ya an email on the extra pin, it's for a SPDT relay.

Kenny

[shamansays]

Cool, this was very useful.
