Ford Fan

I picked up a Ford fan from the taurus 3.8l . Having some difficulty finding 70 amp relays. I need some part numbers and places to buy. I will be hooking it up through a switch in the cab. Should I use just the low speed portion or the high side? Every place I went to doesn't carry this big a relay. They seem to think its awfully big and would require large wire as well.
Any help would be greatly appreciated.
Thanks

I have a small, black 70 amp Ford relay that I just pulled out of my Merkur. There are 3 numbers on it. The first is 77180, the second is 83BG14N089CA, and the third is V23134-J4-X37. Beyond this, I probably can't help you.

If you want it, it's yours. I know I can get another one before my XR is running anyway. I probably even have one in the parts car.

You do not need a 70 amp relay. Switch the ground instead and you can use a 30amp as the resistance thru the fan lower the amps on teh ground.

Mine is set up this way and works great.

BRING OUT YOUR DEAD

Ok, I've been looking through a lot of posts concerning the Ford Taurus fans. There are a number of posts stating that you needed a 60A or 70A relay to run the high side of the fan. There's nothing concerning the low side. Ken also chimed in here stating that the fan will draw 43A at full spin, and that the factory uses an 8 gauge wire.

Nolan has his wired differently where he grounds the fan instead of the power supply (based on the above post). So based on the above you could only run one speed (either high or low) since there is only one ground wire to switch.

So, if you wanted to do a dual control (low and high speed), you could run the fan ground to a chassis ground, then run a 30A relay on the low side and possibly do the following for the high side:

  1. Have one 60A or greater relay for the high side
  2. Have two 30A relays to spilt the load to the high side
With respect to #2, check the March 99 issue of Car Craft concerning custom wiring you can do.

M.A.D. likes to use two relays to power up one large electric cooling fan. Even though the ISO relays are rated at 20 amps for this application, experience has shown a large fan motor will overheat a single relay. Installing two relays in parallel removes stress loads from each relay and improves reliability with redundant parts. (One relay per fan is sufficient for systems with two small fans). Fans' relays are typically actuated via an engine or radiator mounted thermostatically controlled switch, but you may wish to install an extra manually operated switch on the dash as a fail-safe device.

I say someone brought up a very old thread and if your a Ford FAN you need to be banned from syty anyways.
