how do I wire my new taurus fan ?

[hoobness]

I have a 3.8L Taurus fan, when i remove it I cut the wires just past the plug to the fan. - I figure that way when this Taurus fan kick the dust, it will make it that much easier to replace...

Anyway, what wires are POS/NEG...? there are 3 wires coming from the fan, BRN/YLW, BRN/RED and a BLK (guessing ground) to the plug, and after the plug, 1 of the 3 wires splits off into 2 wires...


Do I need a Voltage reg, is it DC 12V? If anyone knows this stuff it would be great, I know many of you all have figured this out... Im not much of an electrician.

thanks again, hoobs

I know you'll need a relay for it. A couple guys I know used an 85 Amp continuous duty relay (Napa ST85 - Continuous Duty Glow Plug Relay, also listed for use in Golf Carts). Anything similar to that will work fine. Bosch makes some good relay's as well, and are something to look into.

The fans only draw like 30 amps, but when they first come on they draw a LOT more...thus the bigger relay.

Don't need a voltage regulator.

As for the wires, I can't help too much there. I'll try to find somone that might knows, but it may take a little while

Black is Ground.
The two-to-one wireset is high speed.
The remaining single wire is Low.

You can use some jumper cables to test the fan, but watch your fingers and any small animals. You've went with a good fan that moves a ton of air.

Do you have AC? Are you interested in wiring it so it runs on low speed and switches to high when the AC is turned on? I can dig up a diagram for that, and it includes a manual off switch.

You can also search 'electric fan' or 'taurus fan' on this forum and you'll find a ton of stuff, and likely a few wiring diagrams for your install.

RE: Fire up the BBQ grill !!!

This is a great mod. I need to get myself to the junkyard and get me one

After looking at a few diagrams, I like XJNicks the best. I also think its pretty credible _have you seen this electric jeep he made?!!

Anyway, I dont have AC, and am not interested in an automatic temperature controlled set up.

--Ideally I want -hopefully in the same switch- to be able to choose between HIGH - LOW and OFF.
--power to the switch and fan controlled by the ignition. Jeep's off, Fan's off.

In the future Id like to have it on a timer, so after I turn off the jeep it would stay on for a few minutes.. But thats then, I just want it working now...

id probably leave it in the LOW position all the time. Im a guage watcher, (I used to driving beaters LOL) so forgetting to turn it on and the thing overheating is very unlikely.

The black wire is ground. The thicker of the two pos wires is high, the slightly smaller diameter wire is low. I've read alot of things saying that you need some $40 80 amp relay, and after spending a full day trying to track one down w/o ordering it, I finally asked my mechanic what the big deal is with these relays. He said that such a huge relay is not necessary and to just go with a 30 amp or so relay. All that extra draw at startup is normal with several automotive accessories, and will not hurt the relay. Well I've been using a $4 Hella relay rated at something like 35 or 40 amps for several months now with no problems. I just have a simple on/off switch for the high setting and have never bothered with the low setting. I'll probably install a thermo switch when I install a 4.0L this summer, though...at that point my cj won't be as jerry-rigged.

SOA CJ7: too top heavy?

I know about 10 people who have burned up 30 amp relays. However, I also have heard of a few people who have gotten away with them.

I just wouldn't want to take the chance of being stranded somewhere when a 30 amp burns up. The amps needed at startup, for the fan, is somewhere around 100 amps or more usually. Yes, a couple seconds of that doesn't seem like that big of a deal...but a few seconds to us is like a few thousand seconds with electricity (yes that's not exact, but you get the point). That's tough work for a 30 amp relay. I don't know though...it's kind of a tough call, unless you can find an 80 amp for a lot less money (which isn't all that hard if you get lucky!).

Can you post a link to that post? That's probably some good info to have . Thanks!

I've got a 3way switch on mine now (high,off,low). I've just got low hooked up which pulls plenty of air to cool my 2.5L. I rarely turn it on onroad, it stays right at 210 without the fan running.

I too thought I would never forget to turn the fan on, until I jumped in the jeep to winch a buddy off the rocks. Forgetting to turn it on, I set the manual throttle at about 2500rpms and began winching. BOOM Blew the top tank out of the radiator. Blew the hood up a little, luckily I wasn't very close to the steam. Live and learn.

Ya, mines wired so I have High, Low, and Auto. That way I can't forget to turn it on...or accidently have it bumped over to off without me knowing.

Are you still using the factory fan, and using the taurus fan as a pusher, or nothing but the taurus fan as a puller?

 

[Bounty__Hunter]

88Wrangles, have you considered a manual off switch in case of a water crossing? Or do you already have one?

I took off the mechanical fan and run only the Taurus fan. It can't be run as a pusher AFAIK because the fan direction can not be reversed.

RE: Ok, I

88Wrangles, have you considered a manual off switch in case of a water crossing? Or do you already have one?

I have considered adding a seperate "off" switch. I just didn't want there to be an "off" on the main switch because I didn't want to accidently leave it on off, or have it bumped and turn off.

Right now I just have a little 'quick disconnect' where I've wired it into my fuse panel. And, the trucks pretty tall, and on 44's...so it's not like I'm going through stuff too often that would cause the fan to be under water.
