Ya know, I ALWAYS just buy the expensive, well made item. The ONE time I try to save a few bux I get bit in the ****.

Setup: Sal's Old School 18" E-Fan, NO wiring, just the pos/neg wires on the fan

Purchased:
Hayden Thermostatically controlled fan harness (has the thermostat that slides through radiator fins)

Problem: Fan will not come on when engine is hot, nor will it come on when A/C is truned on.

Fact: Fan does work. We jumped it straight to battery and it's money. Tried 2 different Bosch relays (thinking maybe the new one was shot)

My wiring:
I have painstakingly reconstructed my wiring. The colors of the lines are the actual colors of the wires on the actual Hayden unit. If ANYONE has done a DIY E-fan and used this controller, please take a look

Per Hayden, relay wires:
Black: Good chassis ground (I did this to my battery instead)
Brown: Either terminal on the thermostat
Yellow: Any 12Volts Key Activated source
Green: A/C Cluth Relay
Red: Battery Power
Orange: Positive FAN Motor, connect negative of fan to good chassis ground.

How I wired:


Can anyone see anything wrong with this. After 3 hours of toying with it I had to throw my stock clutch fan back on. I am NOT a happy camper, but if I'm overlooking something and I can get it to work, THEN I can be all cool and say "Nice E-fan buddy, but I paid 1/2 of what you did"
If I fail miserably , I'll just do the LFP and consider this an expensive lesson learned.

THANKS GUYS!

 

One note.........you better use a 30amp fuse on low and 40 amp on high. That thing will be popping fuses left and right with only a 25 amp fuse.

i know i still have my JDM wiring instrution book and ill try to scan it or even try to mock up something for ya on here if i can
but i cant get it till tomorrow if you can wait a bit

 

Per your drawing that is not what you are doing. You simply connect the relay to the + side of the fan.

is the yellow wire suppost to go through the thermostat switch?

according to this diagram, and others that i have found, it doesn't:

Edited the orange wire comment. It was hooked to the fan positive per my drawing.

 

No it doesn't. The other side is the Brown wire, as indicated in my drawing. One side of teh switch is the yellow igniton, the other side is the brown to the relay.

 

what is the part # of the hayden kit?

 

Whoa...

The problem is with your thermostat!

You have the type that slips between the radiator lines. There is an adjustable temp screw near the relay. Turn it all the way down. It should kick on.

ALso, on my setup (which I said I would take pics but totally forgot) I only have 1 wire going to the fuse box under the hood and that is for the A/C Relay.

I'm not sure why you have the thermostat going to the fuse box. that doesn't seem right. (however I wired mine a year ago so I'm not positive)


Can you scan the wiring schematics and we'll tell you were to put all the wires.

EDIT --> I just looked at the wiring schematics link. Is that IDENTICAL to yours? If so the problem lies in your thermostat. It should go to the control box, not the fuse box (as it looks like in your diagram)
I think my kit was hard wired into the control unit. To plug it into the fuse block I'd have to cut them.




The only problem I had with my kit is I kept blowing circuit breakers. The fan would kick on for about 2 seconds and then turn off. I upgraded to 14v and a higher amperage, problem solved.

 

I'm thinking the thermostat NEEDS to go to the relay. The thermostat (when it hits the preset temp) will close the loop and send the electricity to the fan. Once the radiator cools the thermostat will open the loop and stop sending electricity to the fan.

I'm not trying to flame here, but it doesn't make sense that the thermostat is hooked up to the fuse box.


Again, post the wiring schematics that came with the Wiring kit. We'll hook you up (pun intended),
Okay, I just clicked on the wiring diagram above, is that IDENTICAL to yours?

 

also I think you ahve the A/C wire in the wrong place

 

okay, last post.. honest.

I have a ton of stuff to do, but Next time I visit the truck (I NEVER drive it) I'll take pics and draw up the wiring schematics.

 

Menace your white wire is going to the 12 V Switched power, and then I see a red wire with a connector just dangling there. That red wire should be your A/C relay right? I even looked in my owner manual and sure enough the one I am tapped into is the A/C relay.

As for the thermostat going to the fuse box, it makes sense to me..follow me here.

FROM THE FUSE box
You have a 12V Switched power going to one pole of the thermostat. The other pole heads to the realy. When the thermo is cold it is OPEN, not allowing the 12V from that ignition source to get to the trealy. Once it gets hot it closes the circuit and current flows fom the fuse box, through the thermosta, down the brown wire, and to the realy where it energizes and the relay grabs 12V from the battery and turns my fan on. You with me?

It makes sooo much sense to me, but it isn;t working. Tried a diff relay too..still no dice..

GRRRRRR!!! God wants me to go with LFP.. I can feel it!

Thanks for ALL th ehelp gang. You guys rock.
Off to bed..
I'll scan the Hayden schematics tomorrow morning.

 

don't give up on it! scan the scematics and we can figure it out, there is no sense in paying $00 for an e-fan.

 

Here's the Hayden wiring diagram if it helps. I have to figure this out
