hi... is there a ignition 12v i can wire fal's to ?

[j00ni3]

my friend has a 96 s14 and we are trying to install fal 210s and i wired the fan to the blue wire with the green stripe under the fuse box ( the ac.rad fan one )

and it would not work, i saw and searched online and it would work with the stock ac fan but not this.

i think the fan amp draw is too much or something because

when i try to start it ... the breaker ? i think i don't know the cap thingy; clicks and the fans would not budge... but when i just wire it to the battery it works ...


is there anotehr 12v power source i can hook it up to ?

and if there is can you tell me exactly and how to hook itu p ?

im NOT very good with electric work so...

i searched and they were talking about the starter wire but how do it hook it up ?

is ther eanother line i can ?

also when i was wiring it to the fuse box... i saw a ground wire and a white wire with a red stripe... so what i tried is i ground the fan and linked the white wire with the red stripe to the plus on the fan it didn't work...


maybe if i try to wire it to the bottom and put the cap on ( the blue cap on the wires; the breaker thingy ) ... will taht work ?


if im not so clear just ask what im trying to say because im realy frustrated and the sun is gone and my friend needs his car by tomorrow... also i would look at my car because my car has the fal setup but it's at the shop so ...


thanks guys again

get a 4 prong relay and wire it that way. its safer and u wont blow fuses.

Okay, electrical work is the most difficult type so stop poking around if you don't know what you're doing.

Go download a service manual for your year from zeroyon.com. Look in the EC section, under fan control.

I don't know how the FAL is set up, but the stock fan has high and low output. Your fan should have high, low, and ground. Hook high and low to the wires listed in the FSM. You can ground it by hooking it up to a good ground on the body, or tap the ground wire in the fan control.

Getting a relay is also a good idea. Hook that to a switch in the cockpit and you can manually flip the fan.

i have an inline fuse... also i wired it to the high in the fuse box... his car doesn't hae abs and the only fuse thing in that row... took that out... hooked the 12v to where the blue green wire was..... and nothing... all i here is tick when i turn the car on;the relay
i was reading the fsm... and because im so frustrated... call me brain dead..

so help... i tried what you guys said before i posted... what other options are there?

[g6civcx]

What is the "fuse thing", a relay, fuse, or fusible link? If it's a big square thing then it's the relay. Put it back.

Look for a white with red stripe wire. That's the power lead for fan low. Hook that to your fan. If your fan has a high setting, hook that wire to the brown with white stripe. That's power for fan high.

You need the relay because the blue/green wire is just a low current trigger from the ECU. It doesn't have enough current to power the fan. The fan draws current from a bigger circuit. The purpose of the relay is to use a small current to control a big current. Otherwise you'll have huge currents flowing through your ECU and you don't want that.

[j00ni3]

sorry i got everything mixed up ... it's the relay for the hi on the rad condensor fan... i took out the blue/green stripe wire out and replaced it with the wire from the fan

i actually followed exactly how this guy stated on this website

http://www.240sx.org/links/installs/efans/index.html

[g6civcx]

Read this for additional info: http://www.zilvia.net/f/showthread.php?t=104059&highlight=fan

A little more info about the fan control circuit for you.

The ECU has 2 wires coming out of it for fan control: blue/green for low and orange/blue for high. When it wants to turn the fan on for low, it grounds out the blue/green wire and pulls current through the fan low relay. Then the relay triggers a larger current to flow through the white/red wire. When the ECU wants to turn on high fan, it grounds the orange/blue wire and the high relay push high current through the brown/white wire.

If you want it to work like stock, hook the fan low wire to white/red and fan high wire to brown/white. You can ground it by hooking up to black wires or just hook it to a bolt on the radiator support.


What that guy did is he tricked the fan into thinking that the ECU is always sending a low signal. If you manually ground out the blue/green wire, the fan will think that the ECU is always sending a low signal. So the whole purpose of the writeup is to pull out the fan low relay, ground out the blue/green wire, putting the relay back, and then wiring the fan up like I just described above.

[j00ni3]

ok i sorta understand where you are going .

but the fans don't have a hi lo...

from what i know...

it has a thermo control but my friend doens't want to put it in... he just wants the fan on whenever the car is on.

so if i want the fan to blow on high ... i just hook the positive to the white/brown

and always on low on white red and just ground the fan on any part of the car right ?

[g6civcx]

If the fan only has one input wire, it only has one speed. It doesn't matter if you plug it into the low or high. It will just pull a predetermined amount of power and work at a predetermined speed.

What I would do is follow the instructions in the link and ground out the relay like he says. Then hook the input of the fan to the white/red wire and it should always be on with ignition.

You can ignore the high wire because you don't have one. You can also hook it up to the fuel pump, or to the accessory terminal, but since you already have instructions for the fan that will be the easiest way.

[j00ni3]

hey g6 thanks again for the all the help...

i did just as the instructions told me step by step ... checked over all my wiring...


now the thing doesn't want move... i mean i don'tk now


and you said hook the input the 12v from the fan i assume into the white/red...

now do you mean hook it up to that wire from the bottom so the relay can fit?

or just take the relay off and hook it up to wire itself and it will work ?

cause i tried the second and it didn't work ..

[g6civcx]

Okay, this is what I would do if I were you.

1. Make sure the ground on the fan is good. Check it. You can use a bolt on the radiator support and make sure it's getting a good solid ground.

2. Check your fan. Just take the power wire and touch it on the positive battery terminal. The fan should come on. This is to check that your fuse is still good. If it doesn't come on then you have problems with the fuse or the fan itself.

3. Put your relay back exactly as you found it. If you hacked up any wire, pigtail them back together like the way you found them before.

4. Hook the fan wire to the white/red wire. Start the car and let it idle. As the engine warms up, the fan will kick on and off. If it doesn't do this you need to check your relay.

5. If you can do #4 successfully, then start with step 2 in the link you posted and follow the instructions there.


The relay has 4 wires coming out from under it. My step 4 has you hooking the fan up to the white/red wire. His instructions then has you pulling the relay and popping the wiring underneath out. You snip the blue green wire and hook it directly to chassis ground. Then you put the wiring back and put the relay back in.

[j00ni3]

oh crap.... i have to ground out the blue/green wire i cut right ?

so just connect that wire to the ground of any part of the car right ?


wow... maybe that is the problem ... am i right ?

[g6civcx]

Yup. Crimp the blue/green wire coming from the relay onto an o-ring for ground, or you can just cram it under a bolt. That should complete the circuit and let you pull current through to the fan.

[j00ni3]

ok.... so here's what i've done...

now i just grounded out the blue wire and it didn't work so im just wondering what went wrong...


now i did everything up to the wiring part

1 take out blue.green wire
2. put input wire where blue.green was
3 put relay back on
4 ground out fan to body
5 ground out blue.green wire to body

now... i don't think i did anything wrong ...

g6 did i do anythig wrong ?

i mean the fans are new so it pulls

and i just came back from ground out the blue.green and it still didn't turn over... i put the key in the one position nothing, started the engine.. nothing


what can be wrong.. should'n't the fans come on even just on the on position ?

i mean this mod has nothing to do with the a/c button so ... i mean what can be wrong?~~~

i was careful with the wires... also the a/c fans worked so .. AH~~~~~~

help

[g6civcx]

You did the wiring wrong. The input wire should be hooked up to the white/red wire. This is the wire that turns on the fan. Like I said above, hooking it up to the blue/green wire doesn't do anything. The blue/green wire should be reinserted back into the relay, and the other end should go to body ground.

What you did is grounded both ends of the fan. There's no current going through it.

I'll say this again one more time. Put the relay back and all the wires exactly as you found them. Follow the white/red wire from the relay and connect the input wire to the fan to this white/red wire. Follow the blue/green wire from the relay and snip it. Ground the end that goes to the relay. Wrap up the other end and tuck it away.

At this point if you can't get it to work, I suggest you get somebody who knows a little bit about electronics to help you. Everything you need to know is there. It's not hard, but it's not easy if you don't understand how a circuit works.

[projectRDM]

g6, congrats on your patience. I would have sent the kid a load of feces after the second post.

[g6civcx]

Just send me the feces. I probably deserve it.

[j00ni3]

sorry g6 and thank you for help me so much

i'll try that.. hehe... thanks again ... and sorry too .. :mepoke:

[g6civcx]

Don't sweat it. I don't think it's your fault. We had this question before. The instructions are a little confusing. Maybe I should rewrite it for him.

[j00ni3]

ok g6 ... before i go ahead and do this

let me make sure

imna go put everything back
1.cut the blue/green and then ground it from the relay ... and tuck the other end in
2. question here... replace the white/red with the fan input? or splice it in with the white/red
3 ground the fan

now with the ignition on the fans will start


woo hoo ~ haha... thanks again g6...

[g6civcx]

#2 doesn't matter, whichever is easiest for you. You just need to get the power from the terminal to the fan. I think it's easiest to follow the white/red wire and splice it up to the fan wire.

Good luck.

[j00ni3]

while we're on this... hehehe... sorry g6 but maybe this will give you a headache or not...

with the extra condensor/rad fan laying around... can i hook it up with the front of my condensor; being that there is no room in between the rad and the condensor; and the FALs covering my whole rad

would that do any more cooling to my engine ( and condensor because who wants warm a/c in burning hot summers) ... im running an all n/a setup

with new internals.

pistons/rods/cams/lift springs/retainers/knifed crank and such

i do a lot of stop of go traffic because of work and school and it does get a little above optimal running temp on the i95 and in manhattan here in ny. cause in the summer there is a lot of traffic and a car right in front of you doesn't do you any good so i was wondering.

i was into computers before and i used a heater core for cooling my cpu and such and i put a puller and pusher on each side and it helped

can i switch the 12v with the g and make it a pusher?

so all in all again will it do any good? i mean in the sense of pushing more air. and yea it will only turn on when the a/c is on.

my fans on my car are not hooked up like my friends car... it has a thermo switch and everything else...

so would that work ?

just hook up the fan to the front of the condenser with the 12v and g switch over... all ih ave to do is test the voltage on the wires which ones which and switch em over..

will this work ?
