Howdy- 95 civic dx, hks TT. When I have the car on with the timer, the radiator fan does not stay on.

Can I just use a diode and somehow send a signal to the fans to stay on when the timer is on?

 

Has anyone else experienced this?

 

my car did the same thing when I use the turbo timer thats why I just sit in the car and I am ditching the tt.

 

how does the timer affect this ? doesnt the fan go on at a certain temp and shut off at a certain temp? are you saying as soon as you shut the car down if the fan is going the fan shuts off but the car stays running ?

The ignition has to be in the on postion for it to get power. So when you take the key out, the tt keeps the engine running but not the fans.

 

are you sure about that ? mine still run when the timer is on .

 

Hah! I asked this question a long time ago and I got dumb answers too. Here's how to fix it.

Honda's use two main circuits that have power when the car is on. One powers things like the ecu and that's the one you have hooked up. The other powers your fan and the AC and stuff like that. You need to run a wire from the turbo timer to BOTH wires for it to work right. I dont' know what colors the wires are but you should take a probe to find the two out.

There will be one wire that has power when the ig is on acc. Then two more will have power when the car is ON. Tap the timer in to the two that come on in the ON position.

HTH

 

my timer has constant, switched and ig and mine works fine

yeh man... so if i go on a long drive and keep the timer on to cool off the turbo, my damn car overheats if its on for like 3 minutes or somethin... not cool.

 

back from the dead, does anybody have any clear instructions on how to do this? My car is overheating because my fans don't come on while the turbo timer counts down.

same thing here. I found out it was just a loose wire..but I really didn't find the need for the tt. I'd rather sit there for a bit and chill till it's time to switch off

yeah man, depends on the car. It's a wiring issue. Even though you have the car still running, there is still another wire to splice into for it to stay on. Mine did the same...even the radio would shut off. A friend, with the same car and tt, would work fine...ended up it was a loose wire on my part.

Are you using a greddy tt?

 

check the wiring again, i used to have that problem, just check the wiring

 

I'm using an HKS type 0 turbo timer.

 

I had the same problem with my ex 97 civic..I remembered that friend who is electrician, wiring something into the relay box under the hood..Now i have 93 civic and i have just gone out and shot some pictures on the relay box..I'll post it up later and i'm trying to explain how to solve the problem.

 

here we go..

on the picture below you can se 3 main relays (92-95 civic)..one of them is cooling fan relay (something like that), on the cover of the relay box is sticker where you can see which relay is for radiator fan..ex owner of the car removed the sticker i don't know why..


when you know which relay is right take out the relay and try wiring together one of those combination..blue or red i don't know which one is right, cause i sold the car month ago..find some electrician who knows what he does.it takes him 5 minutes of work..i hope you can help with these infos


I'm using blitz dc II turbo timer..

 

how would you physicall wire those two prongs together? Do you just tie a piece of wire between those tiny holes? Or did he take the shell off of the relay and somehow wire it front the internals?

 

he just tie a piece of wire between prongs, it's simple

 

I had the same problem a few years ago. What I did was run a constant power to my fan relay. This way whenever the coolant temperature was high enough to run the fan it would run regardless of having the key in the car ect. This was in my G2 integra and the relay was right up front by the radiator.

So basically you are supplying constant 12v to your fan relay instead of a switched 12v when the key is on. This should solve your problem.

 

Three ways to make this work right.

1. Run a paper clip from one prong to ther other on the relay in the fuse box under the hood, like the pic is trying to show you,

2. Or cut the two wires going to the clip on your t-stat housing and splice them together, this will also make your fan run as long as the car is on.

3. Fix your wiring so the fan comes on like it should.

I went with option one.

Thanks I got it to work Finally radio and all

 

Damn i spiced the fan switch wires together. Now the fan stays on the entire time the key is in the on position. However, once i take the keys out and the turbo timer starts counting down, the fan goes off . I don't know what i did wrong, but i can't get my fan to go on while my turbo timer is counting down. It's making my car overheat after hard drives...what do i do???

 

ohh man this is back from the dead.

I never fixed it, my car ended up dying on mr shortly after I had that problem, and im JUST now beginning to piece the car together i feel so out of it, i was too busy with school to keep workin on my car. I was thinking of a couple solutions, ill hafta get back on the ball and fix it

However, if the coolant temp was high enough, the fan would remain on even after the car shut off, correct?

 

OK STOP...one thing that bugs me is crappy electrical advice...you know those fans pull like 15amps of current...a bad or loose connection can flame ur car....so number 1 only get advice from someone who know's what there talkin about..like a car audio installer.....first thing you need to do is test ur stock fans...let the car warm up and the temp rise...see if the fans kick on automaticly..if not fix them either the fanrelay/fuse/or fan motor....if that works next step..check tt install...some cars require 2,3,or even 4 wires for just ignition.and more for accessory's like radio etc....on some tt's you have to add relays for the extra ign and acc. wires....once that is done test again with the turbo timer..remember the car has to be hot enought to turn the fans on...a tip i can give you is to wire a swicth and relay into your stock fan relay...how to do this...i used a switched ign..source from under the dash ran a wire :FUSED: to a switch on my dash..from switch u need to run the wire to the engine bay :USE A GROMMET:..bring the wire into you main relay and fuse box like pictured above...find the relay that controls the main fan..pull it out...now using a probe find ur 12v constant and the 12v supply for the fan...wire the stock relay with 2 14ga wire "i used a dremal and grinded down the plastic at the base of the stock relay very carefully...to solder on the wire no my stock relay can sit flush on it's mount...now wire the stock relay to another relay set up the new relay to trigger the stock relay using the switched wire u ran from inside the car...BAM...now you can turn on ur fan anytime the car is turned on and it will shut off ...by using the relay you can use a small low current swith inside the car and it won't stress any of the electric components in the car...MAKE SURE YOU FUSE ALL CONNECTIONS/USE SOME SORT OF WIRE LOOM/NO BARE WIRE ANYWHERE....i will make a DIY post with pictures and step by step instructions some time.....oh ya not to be rude please don't tell people to stick PAPER CLIPS or stuff like that..first thats retarded..second it looks bad...it might have worked but it's not safe at all ...do you want your hard earned parts and car going up in flames

 

I don't want to start a fight or anything, but my "stupid" paperclip to jump the two leads in the engine bay fuse box has worked just fine for me for over two years!!!

There is still a fuse inside the car that can blow if there is an electrical surge.

Looks ghetto? How, you cant see the paperclip inside the fuse box under the relay?

two or three relays???? boy you like to make **** complicated and more possible for things to fail. rememeber K.I.S.S.
