Using it to control Flex-a-lite FLX 398

Summit RacingSummit Racing Verified Purchase

Using this control unit for my flex-a-lite FLX 398 (16", 2'500 cfm) s-blade fan for my 67 F100. The install was pretty easy and the temperature adjustment process was even easier. One thing I did decide to do was add a fuse on the positive side of the fan back to the batter, the wiring of the control unit is set up so that the fuse is on the ground side of the fan back to the module (that's why I gave em a 4 star instead of 5). Used my touchless laser thermometer on the thermostat housing to verify on temperature. Been running it about a week, no problems thus far. ...read more

2 Controllers didn't work

Summit RacingSummit Racing Verified Purchase

Installed 16749 according to instructions. I feel I'm a very skilled mechanic. Controller didn't work upon initial fan start up. Happened to be going to Reno over Labor Day weekend so I stopped by Summit's retail store. Exchanged the non working controller for another new controller. Still didn't work. Installed a manual switch to prove operation of the electric fan. Worked perfect using the wiring I had installed for the fan controller (pulled the included in line fuse and ran the fan side fuse connection to ground via a toggle switch). I had called Derale tech support previously, and the tech wanted me to test voltage to the Controller. Verified I had 12.8V to the positive wire to the fan, and also 12.8V back (via the negative fan wire) to the controller. Then went online and read similar reviews to mine. Don't know if I can trust this Controller to work long term if I ever figure out how to make it operate correctly. Sourcing alternative controller products as I write this. Beware of this Controller.... ...read more

Dont purchase this controller. waste of money

Summit RacingSummit Racing Verified Purchase

First let me begin by saying i am an electrician. This product is junk. I had two fans wired onto this circuit each pulling 4.7amp. Well after 350 miles of use i began blowing relays. I figured the relay included in the kit was just faulty so i put in another 40a relay (same as whats included in the kit) but that relay died instantly. I began checking for a short circuit and found one, inside the relay holder... what a joke, time to make my own harness like i should have from the beginning. ...read more

In use for only 2 weeks, but so far working as advertised. I appreciated the amount of wire provided and the clear instructions.

just ok

Summit RacingSummit Racing Verified Purchase

the relay and adjustable switch work great but as my car was overheating due to another issue the fan was running non stop and this continuous running caused the connector at the fan to melt and lose contact resulting in no fan and further overheating it seems the wiring should be a heavier gauge and a better quality connector would help.
