fan wiring help

I know this has been covered but I need some help.

I installed dual fans and made my own wiring setup. These are not contour fans. The fans run but I think I did not wire everything up correctly. So before I break something I just wanted to get some input.

I have the fans wired via the following...

Power : starter solenoid - to breakers - to relays - to each fan
Key 12 v : C on starter solenoid - relays - to fan (not sure if this correct)
grounds : connected to battery via dedicated ground post

Thanks

I wouldn't 'slave' off the s'solenoid, run a separate one.
What gauge wire did you use? What amperage on the 'breakers'?
IF, they run when the engine is cranking. That's NOT good.......

I used one of the red/ key on wires from the fuse block (don't remember which) I think it was the cigarette lighter passed that through my toggle switch to override for water and used that to trigger my relays.... other then that you are hooked up the same way I was until I wired it into temp control with an override. ( I didn't mind one fan running all the time)

My only other suggestion is to put 2 toggles in line leave one on and one off and only use the 2nd one for when your crawling or its really hot. this is basically what led me to redoing everything.

I used leftover 10ga car stereo wire (red and black) for my feeds since the strand count was SOOOOOOOOOOOOO much higher then standard stranded.

and BTW if the engine is warm enough mine run when I crank and I haven't had any issues.

You don't have them hooked up to a temperature probe to turn on at a set temp??
The lower DCV to your starter and your fan motor's while crank'n, ain't good for'em.........
AGAIN, what gauge/type of wire did you use?

The gray wire goes to the temp probe and the wire sizes that are listed in the diagram are what I used

Good deal on using the correct ga, sizes. MANY, don't.
You want the fans to run in the run position of your ign. switch. Not on the start position. Someday, you will need every bit of 'juice' that battery has left to start.
Also, have a kill switch under the hood just in case.

no actually just got off the range (always makes me happy) and came back in to see if matt needed any more info (yes I know him) and all you were offering were questions that he already posted answers to...

untwist your panties and support the forum....

Thanks mike, I have some free time tomorrow so Ill see where I can connect the yellow wire. I think I have a couple wires that don't go anywhere under the dash. I'll look and see if the parts stores have any good switches. I'll post back and let know how things go

Yellow wires in your diagram should be going to #86

Use the yellow accessory wire off the ignition switch, it should be off during cranking.

However these will run all the time in the Run position! Don't you want them to run only when the engine gets hot?

Looked under the dash last night when I took the dog out. Only found a large red wire not connected to anything. The rest of the wires had connectors. I will look for a yellow wire today.

They should only run when the temp switch closes the circuit, 200* - 185*?
