Interesting. A little pricy and it has to be mounted in the cabin but its good to know about options.
There is a tech artical on this . After spending more money than I care to remember on 3 differant controlers this one WORKS . Check it out you will be happy with out come . Many froms member are using these units.
71 Gold yes I supply this controller with each of out Tri5 Chevy rad support systems which uses twin Taurus fans. I have been building custom cooling systems for over 15 years and have used every controller on the market and by far the is the best one I have found.
...how about the...single 2 speed Taurus fan...like most of us run on our cars? I am not knocking anything you have done with other fans, i'm just comparing apples to apples. ...Frank...
Frank the only difference between running 1 fan or 2 is the number of relays. For a single fan you run 1 relay for a single speed and 2 for a two speed application. I was speeking for the durablity and flexablity of the controler.
i understand how the...1 fan...2 fan and 2 speed fans work...i am not questing the...durablity and flexablity of your controller.I amasking ...have you ran a... single 2 speed Taurus fan...with your controller? Jay and I have ran several different controllers on the...single 2 speed Taurus fan...and they failed in just a short time. this fan has a monster high side and if you don't have the low side running when the high side kicks in, you will have problems. also the low and high side can't be on at the same time. I have burned up 2 fans, several relays (1) 75 amp) and melted some wires. as far as it goes,you can't beat this fan for cooling. it just has to be wired correctly. the way our setup is...the low side cuts off at the same time the high side is activated. also when cooling down the high side shuts down when the low side activates. ...:Handshake...
Dave As I have said before I have spent more money than I care to remember on fan controlers just to find out they ALL were junk after a short time. At the same time if the one you are using is working for you then by all means keep using it . For me its all about the number of fun tickets ( dollar bills ) I can keep . The OEM have larger brain trust than the after market . If this controler has worked for all these years on all the millions of cars that volvo has made I think it will work on my mav that I drive about 2 - 3000 miles a year . Just my thoughts Jay
To power my Taurus fan I used a simple FlexaLite 20 amp controller that energizes an 80 amp relay and, in turn, the fan. Don't forget about upgrading the alternator.
Alternator When my alternator wasn't charging I removed the voltage regulator and replaced the original (?) alternator with a 1-wire 100A one from Summit. An expansion fuse block fit nicely where the regulator was.
One speed at a time. My homemade control box connects directly to the battery. With the key on (engine running) the fan will turn on high speed. With the key off (engine off) low speed will turn on to cool down the engine.
Lots of good ideas in this thread from guys that have done it. I assume your 80A relay switches a circuit that's also fused at 80A? Sounds like you are switching the fan from off to high speed when the engine is running. How long have you had it set up that way? Just wondering about durability of the motor. Thinking ideally a controller would switch from off to low speed, and low speed to high speed, AND run on low speed when the engine is off but that sounds kind of complex. Oh yeah, then there's the AC on mode too. Have to give this more thought ...
Yes, I have an 80 amp auto-resetting circuit breaker feeding the 80 amp relay. My control box consists of 2 relays (80 amp & 30 amp), 2 circuit breakers (80 amp & 30 amp), and the adjustable temperature controller. The 30 amp relay is energized by the key ignition wire. No power on the ignition wire, the 30 amp relay's NC contacts connect the temp. controller directly to fan low speed windings. When the ignition is on the relay's NC contact opens, removing the controller from the low speed winding and the relay NO contacts close connecting the controller output to the coil of the high speed 80 amp relay. I just installed this and the Taurus fan last winter but I used the controller with my previous electric fan for 8 or 9 years. Had these parts laying around so I thought I'd do something useful with them. I run a 180* thermostat, the car normally runs 185*. Controller is set to turn on at 195* and cools down to 180* then turns off. Runs for about 30 seconds, gotta love those Taurus fans!
