I just got my taurus fan installed finally, and it does work, I have it directly wired from the battery to a switch then to the fan. I know this is not the best way to have this set up, I could feel the switch getting warm to the touch, I did some reading, and a thermostat of somekind, and a relay I believe are a couple of things that I would like to have installed but I do not know where to begin....

 

Yes. Definitely run the power to the fan through a relay.
Also, that line should have a fuse on it.

A thermostat could control the relay (or may have a built in relay, I suppose), and the fan could then come on at a preset temperature, so you wouldn't have to manually activate it.

 

You're pulling too much power through the switch... What you need is a relay.

check this... It says foglight, but replace it with the fan motor... Same principle...

Relay takes a small ammount of power, it effectively handles the large ammount of power that the fan, foglights, or anything else takes...

Get the idea?

Instead of using the parking lights circuit, use a circuit switched by the ignition key...

 

Yep, got the idea. Can you use relays off of other vehicals, or is that something you should purchase new? Are all relays pretty much the same or are there different types with different voltage amounts that they work on? Sorry for my ignorance on the subject..... Just learning the electrical end of things....

 

relay that works good is foglight relay

i'm using foglight relay on mine's and everything seems to work perfectly, except i'm not using switch.. just direct to positive terminal on stock coil

you should be able to get them at kragen, NAPA, autozone or other autoparts store

 

yeah, as long as you use an automotive (or 12 vdc) relay that'll support the amperage (just get an automotive relay ) you'll be fine.

 

Alright. Thanks man!

 

A relay is a relay, your standard relay is around 30 amp. some of the higher power handling ones are 40 amp.

You wont even need all of the 30 amp so dont give it much though.

You can use one off anything and they all pretty much have the same pin numbers weather bosche, no name, 4 pin or 5 pin.

I can give you the pin out if you need it, if you decide to use a used one and dont know what number correspond to what poles and if their is not a diagram on the relay.

^^^ This is fairly true in the automotive industry. However, this is not true in a general sense. I have a 5 volt, 1A relay sitting beside me at this moment

 

I just picked up 2 30 amp relays, they both have 4 places to hook up wires, and a couple of inline fuses, that should do the trick now I am guessing. Again thanks for the info.

 

How about:

Its in and working, just need to get a thermostat of somekind.
