Dual electric fans? Burning through thermostats? here's your answer.

[Tenchuu]

so i have tried shitty (hayden) to nice (SPAL) thermostats to control my Dual FAL pushers and all of them burn out (the SPAL lasted all winter though while the haydens worked for a couple of months) so after putting a little thought into it i found out a way to bypass all this bullshit about replacing your =fan controllers, and in the process not spend $200 for a FAL one (mainly cause i would be out a car for a few weeks while it came in)

so i went to the local parts house and found a shitty hayden temp sensor as shown:


after hooking it all up i run the output signal into two relays:


note 30/40A relays

and then i hook up a maxi fuse block (small fuses blocks were melting in 1/2 due to massive heat, i went through about 5 of those things since last fall too):


so basically i am just using the thermostat as an "on" signal for the relays that then pipe the power through 14 gauge wire to the fans and back out to the ground near the fuse box under the hood. i will let you guys know how it holds up, but i figure at worst i will end up replacing relays now instead of e-fan controllers.


anyone else do this? anyone else have problems with e-fan controllers melting down on them?
