Here's the motor itself with the windings.

Looking at the details inside the motors, it's definitely German. Everything is precise and well fitted. This is definitely NOT a cheap electric motor like I've seen in parts house fans.

I guess this means I now have an extra fan. If anybody needs a slightly used monster two speed fan motor with a 20-1/2" blade attached, I've got a spare. You will need to open it up and glue the cover on the electronics.

It should still work but you're on your own when it comes to building a shroud for it. I suggest a VERY sturdy frame to hold the motor.

Scary thought, but I wonder if that fan works as part of the CAN BUS system.

Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first. Life was a little easier when I was just a wrench.

I don't know which system it feeds. My shop foremen all said it was feedback from that 4th line. I'd lean more towards that over the ME.

Front SAM maybe?

Can someone with a little more knowledge tell me what the green resistor thingie is for?
I assume the electromagnet looking coil is there to provide a charge to the plates inside the windings.



The light green 'box' near the input is a 4.7uF capacitor. Likely just to provide additional decoupling for the circuitry.

I'd need a better picture of where the traces go to SWAG what the coil does.

Most fan controllers work by changing the frequency that they turn the fan on. If you turn it on and off really fast, the fan will average out to half speed. If you leave it on a little longer than you leave it off, it will run a bit faster still. That's what all the circuitry I'm guessing does. You also want big capacitors (the two big blue ones) on the output to smooth the output voltage a bit, and provide help when you start it.

I'm considering a fan like this for my truck (tired 318)... with a 6 blade fixed fan, good shroud, and new 3 core rad, it still won't really cool itself off at idle

If you ever find yourself in a fair fight, your tactics suck.

Well today i had a chance to rig the fan up on the bench.IMO blows a whole lot better than HHR fan i have one so i can talk.Hhr fan temps got up to 210 at idle.This fan sucked an ink pin to the fan on the bench.It's pulls a lot of amps so be ready.Will be in the 90's tuesday i am waiting on one wire from mercedes i like mine to be neat looking.It takes a while to ramp up but when it does look out.I thank up again FEETS.This will solve my problem now i will be able to run my A.C.I will post pictures of my install monday.

I wonder if the trigger voltage is just a positive reference voltage and can be sourced with something as small as a 9 volt battery.

In the midst of installing my A/C compressor, I've realized I'll need to order a new e-fan so this purchase may be coming up sooner than later.

I never thought about the 9 volt battery. I might try that and see what happens.

Gtx, that fan will move a lot more air once it's off that bench. I'm still waiting on a friend to bring his anemometer over to measure the air velocity coming off the fan with the radiator in front of it.

I did set it up like it was mounted to the rad.It did move lots of air in the up right.

Mine moves a lot of air. If the fan is running I can open the hood and watch a dollar bill flap in the breeze by the windshield.
I can also feel it blowing air out from underneath the car.

They're beasts!

Does your scoop open up into the engine compartment?

If so I wonder if there is a flow of a air out of the scoop when the fan is on and the hood is closed.

It is open but I haven't checked that yet. I doubt it. The intake plenum blocks the opening.

Thanks for the info,I put one of these fans in my dart with a 383 and it works great,had this fan laying around for a year or so. I instaled it about three months ago,wired the pos side switched w30amp adj relay and close looped the small wires..it works but things(wires & relay) get a little warm..fan will fit in abody big block with slim radiator im using 04 mustang with 08 c350 fan...have 1/8 or so fan to pump.

You don't need a relay on the power wires. I'd suggest stepping up to a larger wire and a direct feed from the battery or alternator. A wire getting hot can burn your carn down. I'd hate to see that happen, even if it is a Dart.

Common the negatives of the 9v and your 12v car battery (as long as the fan controller is looking for a 0v reference), and you should then be able to use the positive feed of the 9v as the trigger to the fan. I'd assume you'd be able to hear the difference in speed, but a tach would be nice to place on the fan blade base and get a real appreciation for the difference, if there is any

The common ground is what I was thinking. As long as I don't cross the other terminal with anything else on the car I should be good.

I'm out of 9 volt batteries. I was looking for one on to use in my multimeter this weekend. Gotta get more.

Yea. I'd hate to read a thread about you trying to charge a standard 9v battery with your 12v car battery... or worse- your alternator. That would probably end ugly.
