Electric Cooling Fans
Hey all
got a silly ? went and bought a dual electric fan from a 94 ford probe and the connectors have three prongs on them. pic follows:

If I put power to the single prong and a ground to either of the other two the fan runns fine. Does any one now what the third prong is for or can I just tape it off and forget about it
Thanks in advance

Most late model Fords use 2 speed fans. Slow for engine cooling and high for a/c. Are you sure that you are grounding the right post when you check these? You may be powering one speed and grounding it thru the other. 2 hots/1 ground.

Is this enough fan to cool an air conditioned '73 390 F100? Actually, I am looking for any good suggestion to replace the current setup. Right now, the fan is bolted directly to the water pump and I'm thinking I could save a little gas if I converted it to electric.

Jim-
Use a clutch fan from another boneyard vehicle. Electrics are great if you get into deep water since you can turn them off.

Hey all
got it figured out and there are two speeds to both fans. I took and hook the bigger fan up on high speed to the switch and the smaller one on a toggle that i can control both speeds seems to be working so far

If you take the harness apart, you'll notice that after the connecter they just run into the same wire. Basically the 2-speed part of the fan is just current-controlled, i.e the relay will send half power (6v or so) to one prong, and if full speed is needed, will send an additional 6v to the other prong, after the connecter they run into the same wire, making full voltage to the fan, giving you full power.
Pretty easy, actually. If your just hooking them up to your truck just run power to both prongs, don't worry about messing with the trying to get the different speeds working. (you'd need 2 fan controllers at different temps, and a resistor to cut each to 6v, so when they're both on, you'd get 12v)

Well all I tried it every way i could think of but still didn't work right put a 30 amp relay in line with the fan on high speed and it burnt the relay out with in 1 mim does anybody have and ideas on why the power wire to the fan would get so hot.
Thanks
Thanks
