Trying Flex a Lite Fan Controller

Just thought I would give this controller a try on my Traurus Fan..

PART # 31165 from summit

 

i am going to do the same taurus Fan swap after i do the 3g alternator swap

make a sticky you should add it to the taurus fan sticky ??

 

wait till it tests out for a few months first, how many controllers you been through on that thing now? cant say im doing much better with the one on my truck.... hope this one is the winner.

Well this is # 2 the last one burnt up after 3 month and the a$$ hole would not make it good SO on to #2 next test ..

are you useing a relay or do you have the fan hooked directly to the controlers?
if you not useing a relay then you will keep burning up controlers. fords factory fans have an amparage spike when they first turn on of 40 to 60 amps. the realys or transistors in the controlers wont be rated higher than 30 amps on the best of them. the fan will burn the controlers pretty fast. put a 60 amp or higher realy in to controle the fan. or use two 30 amp relays wired in parellel.

 

I spoke to Flex-a-lite about the controller some time ago. They told me that the internal wireling itself couldnt handle the load required for the fan. Using an external relay would be the same as utilizing a cheaper fan thermo switch with external relay. Dakota Digital now sells a controller with a built in 70 amp relay I want to try. But that will have to be in next years upgrade budget.

...and they say you will still need..."RLY-3 (0-70 amp)(not included) will be required for dual fan or two speed fan operation"...

so what do you get for...$114...

Both of the controllers I have used are soft start controllers and a relay were not required . The soft start controller starts from 10 pct. to 60 pct. fan speed and as temp. goes up the fan speed will go up to 100 pct. As per all of the driving inst. in the kits NO relay were needed . But maybe a relay may not be a bad idea ..


Jay

The soft start does away with most of the high amparage spikes

 

Jay,
i did not about the soft start thing. my guess would be then that the ford fan still has too much of an amperage draw for those controlers. for the cost of those controlers you could use two of those cheapy ones that have the borbonic tube and a knob to adjust temp, 4 relays to use the two speeds that the fan has. i suspect that you have allready ordered the new controller so lets see how it works out for you.

 

"Included is a 70amp relay, enough for even the most power hungry of cooling fans"

Yes if you are wanting to run dual speed then you will need to buy an additional relay. Since I already have a 70 amp relay with my current setup, the additional one that comes with the kit will be used to run the second speed. The primary advantage I see in this system is packaging.

1 controller
1 temp sensor (existing gauge)
2 relays

The alternative

up to 4 relays
up to 2 controllers
2 temp sensors (in addition to gauge)

 

i am going to do the 3g alt swap tomorrow and i just bought the fan controller and was wondering what other relay's i can use and there #'s to tell them when i'm at the store so they can find them //// because they could not find one because they don't say the amp's ??????

wow 40 bucks

 

it's the only relay i've found that can handle the load.
Jeff and I helped Earl install his Taurus fan today...and we installed that relay...
