Hi FF!

That's excellent!

I would speculate that the other info needed would be current draw per fan, any interposing hardware between the PCM<--> fans( if any), and, more importantly whether it's a 3/4 wire fan motor with internal rpm sensing. Someone with access to the 2010 electrical schematics would be able to help here. The PCM is the controller.

Have a great weekend!

Cheers!

That is correct, we do not need the temperature sensor. Here is what I received from Brian in response to Winsors post:

For starters our PWM controller and relay kit have detailed instructions on wiring, our PWM also has an a/c trigger wire that turns both fans on when the a/c is turned on so you won’t have to worry about that. As for the temperature sensor if you don’t want to use our sensor the PWM will work with the factory temp sensor that is already in the truck and there is also detailed instructions for doing that, the PWM also has an auxiliary override circuit if you want that, and it also has a failsafe that if the controller fails it automatically turns both fans on high speed. Spal has put a lot into this controller, and we worked very closely with them on the design of this controller to make sure it met all the needs of all our customers in the street rod market.

 

I don't doubt that the documentation fully explains how to wire it in. However, I don't think it's going to tell you where to wire it into your respective vehicle. But like MGD pointed out, finding the correct wires can be located throughout the website. You'll just need to do a little more legwork to get everything in place. The controller is very interesting and likely the route I'll go if mine were to fail.

What I like about Troyer's set up is the ability to operate each fan at different temperatures. It seems to me the Spal controller will operate both fans simultaneously.

 

Hello, Windsor!

Yes sir - it is a single controller - but it has triggering for a second fan - two temp setpoints. Here is an excerpt from the docs (sorry about the C&P formatting, lol)

"When the Low temperature setting is reached, the ‘FAN’ LED will light AMBER,
and the fan will run at 50% or ½ speed. The fan will then gradually increase
in speed as the engine temperature rises. If the high temperature setting is
reached, the ‘FAN’ LED will light RED, and the fan will now be running at full
speed.

When the ‘FAN’ LED lights RED, a negative output will be sent on the gray wire.
This gray wire can be used to trigger a fan relay, an indicator light, etc. If you are using dual fans with the recommended wiring setup (refer to pages 18/19) your 2nd fan will turn on full speed at this time.
If the cooling system is able to lower the coolant temperature approximately 5° below the High setting, the ‘FAN’ LED will turn from RED to AMBER and the fan will slow in speed; at this time the second fan output will stop as well. If the cool-ing system is able to continue to lower the coolant temperature to approximately 5° degrees below the low setting, the ‘FAN’ LED will turn off, the ‘STAT’ LED will light GREEN, and the fan will stop completely."

But - as you noted before - one controller versus 2 in the TP kit = single point of failure.

To all - another bit of good news - this version (V3), has a built-in in-cab indicator output - all you need to do is run wiring & supply the indictors. This is HIGHY recommended. If you pop a fuse you will not know otherwise. The manula discusses this in detail - a good read.

Cheers fellas - great thread! Safe weekend to all!

Do you have the link to where you are getting this info?

Nevermind found it: http://www.spalusa.com/pdf/FAN-PWM-V....PDF#view=FitH

A solid 33 pages

 

Excellent information! I know my fall-back position.

 

I just fell in love. Bye bye troyer

 

FF please keep me updated on this. I want e-fans but I wanted to go this route. I got an 09 so I would think it would bolt right up. Just need to figure out how to control it etc.

 

I havent had any problems with my fan setup, or my customer's trucks for that matter

 

I had Troyer efans installed in 2005 and on a trip to the desert the main one failed and I overheated. I straight wired the unit while being walked through the method while on the phone w/Troyer. This get me home to Michigan and then down to Troyers shop. They replaced both relays and waterproofed the hell out of them. Here we are 5 years later and they work good as gold. I now live in the desert so moisture is no longer an issue. Perhaps they use a different relay and fan system than they did in 2005 but alas...that is the way of technology.

 

I had Troyer Efans at one time, too. The setup originally came with those ridiculous copper rods to install them to the radiator. The setup also ran 30 amp fuses which constantly blew. After replacing those with 40 amp fuses at Troyer's recommendation I started losing relays. They would bubble and blister and melt my wiring. I sent several emails and had phone conversations with Troyer and was always offered replacements at a "discounted" price. Being an electronics tech for several years I just gutted their setup and installed two better rated relays wired with 12 gauge wire to two switches in the cab that I could turn on as needed. Worked great until their fans quit on me...both of them. That was within three years of their purchase. I've replaced their fans with some 16" high performance Jeg's fans and never looked back. I sent Troyer a nice little email to say goodbye to his inferior products and lack of customer service. Sorry for the rant, but that's been a long time coming.

 

Wow was actually going to buy troyers set up, glad I saw this post. I like the idea of using 2010 f150 set up think I will look into this.

 

Jeg's Fan huh, well I think I have to trow away troyer's junk and try your set up, when you get a chance pass me the link. Thanks

 

Good morning!

Lots to choose from. The most robust 16"-ers are not inexpensive, but the claimed cfm and amperage seem realistic (no "3,000cfm @ 9 amps" crap, lol).

Quality, warranty, fan motor manufacturer, etc ... no idea ...

Good luck.

OGTerror,

Here's a link to the fan I actually purchased. They're $10 cheaper than when I bought mine. I've been only needing to run one fan, but will be getting a second one to replace the other dead Troyer fan (both fans' bearings bound up, can't even spin them) in time for summer.

Good luck!
