Alternative Fan Wiring -- A Sanity Check, Please...

[tcrist]

I really do not have any information to help but I do have a question though. Has anyone added (or is there even a) re-setable breaker that can be used rather than fuses?

Is there any practicality in even having them?

Yes, you'll see in my picture that the yellow wire goes to an automatic circuit breaker that protects the entire wiring system.

Is that the little 2 post one on the left end of the wire?

Yes, they're very handy. That's a 50 amp one, if I recall, and sits between the battery and the entire wiring harness (except the full dump to the starter motor). Remember, most of the time there's very little current crossing it, even if you have your fans, lights, wipers, turn signals, and horn all going off at the same time. None of that draw would pass through the circuit breaker, unless the engine wasn't running. They don't cost hardly anything. Click here: http://www.wiringproducts.com/contents/en-us/d60.html

No worries; I might even have one down stairs in the basement. I usually take your advice.

Patrick, I don't think it's a good idea to have your pusher fans wired into your thermo switch along with your puller fans. Since the 2 fans move air at different rates, I think you can create turbulence between the two - which is your radiator- and actually detract from the efficiency of the puller fan. I have my pusher fans on a manual switch and really only view them as decoration. Many don't even wire them in and just let them spin from flowing air.
Besides, taking your pusher fans off the thermo switch will cut down on the big draw you have when the thermo switch initially opens.
Just my dos centavos!

Matt -- you're probably right. I just love the look of the pushers when they're spinning. But you know, when the car's moving they're probably spinning anyway even when they're not getting power.
