JeffB This is a good way to go also: 100% Brand New Electric Fan Relay with Thermostat Hardware Kit 180 TO 200 | eBay

EOD Guy As far as your dia..... it will work as long as you provide a ground to the coil side of the relay. The 30 amp fuse before your on/off switch is a bit of over kill and your relay coil will burn up long before that 30 amp blows

EOD Guy After some research this might be the solution

EOD Guy If you guys are looking to add a delay timer to a relay...... check into a delay timer module for a house alarm system...... most work on 12v and if you use it to control the coil on your fan realy it might just work...... I've never used it for this type app..... but I have used them to control some devices I use in teaching.

66GMC Hmmm ... reading this with interest, and always appreciate EOD Guys product knowlege and opinions.

I searched our NAPA catalog for "delay" (with the intent of finding a "headlights off" delay relay.)
I didn't find that, exactly, but this relay came up with various usage. (i.e. "A/C Comp Time Delay Relay", "A/C & Heater Delay Relay", and more specifically ... "A/C Condenser Fan Motor Relay "

NAPA Echlin #AR-143
NAPA SRP ~= $20.00 CDN

I'm thinking this might be worth a call to the tech line to see if there is an integral timer built in???

Will my wiring configuration work? (see attachment)
08-24-2012 02:31 PM
EOD Guy Yep..... If you already have a system, prob not worth the cost....... I started with zero and was going to have to purchase parts and pieces, temp controller, relays, wire, temp probe, bushing etc..... in the long run the DD was a little more but well worth it IMO

ogre thanks for the info eod,
dakota has always been proud of their stuff
probably a couple of bleed off capacitors that keep the relay energized
a dimes worth of parts and $100 worth of dakota
i'll stick with my plain jane relay set up it

EOD Guy The fan controller I used is from Dakota Digital.....they are proud of it tho" lol..... it was super easy to hook up, came with the temp sending unit, and all the wires/equip to connect it up, it has a fully adjustable temp on, temp off, one or two fans, adjustable cont to run after the key is turned off and most important, IMO, a test mode that allows you to test the on/off temps at any time...... it is a "fan always hot" and the module connects to ground, I like that because if the thing fries all I have to do is disconnect the relay wires from the module and connect them to a ground and my fans are running etc...... just a little insurance. I am very sat with it

That looks like a pretty neat relay/fuse combo, you can get away with a 30 amp bosch type relay, or a 40 amp...... you want the heavy duty contacts that the higher amp relays offer...... now you will protect the circuit with a 25 - 30 amp fuse......

Eod guy

I purchased a SPAL 16" Puller, what specific type relay will I need to use (amps)?

Any specific brands I should stick to or just go to my local retail auto store?

Here is the SPAL fan specs:

Will this type of relay work?

RatPin I too am interested in the "car off" delay.
08-23-2012 09:23 AM
ogre eod guy;
you've got my interest
where did you find the car off delay?
08-23-2012 03:55 AM
EOD Guy No, that's the way I have mine wired....... Mine has a "car off" delay feature. That is it runs for 1 min after I turn off the ing, the run time is adjustable up to 10 min.....
08-22-2012 11:05 PM
RatPin I also am wiring up an adjustable electric fan with a relay. I opted to run the lead to one of the "always hot" open fuses in my fuse panel. My thought is that when I park the truck after driving, the electric fan will be able to run until the engine reaches the adjustable fan's "turn off" temperature. I have had cars in the past that were wired like this from the factory and it seemed to make sense doing it that way. Any drawbacks to this other than the battery may have a little extra draw on it until the fan kicks off?

Well stated/explained, I will get that 3 dollar relay! Your follow-up is greatly appreciated...
