Which wiring diagram did you follow?? Maybe we can figure out where you went wrong?? Or if the adjustable temp controller is bad. My first controller was defective, and I had to buy a new one.cretamk said:thanks for the reply. i have power but the fan only runs when i have my ac fan on. the temp sensor is not working for some reason
Yes, but yo udont want to do that. You would be constantly drawing piower and defeating the purpose of the fan anyway. Your motor would run cool, but your battery will probably die fast, and you will probably overwork that fan. I wired mine up using a cheap thermo controller from autozone, and I have had no problems with it.cretamk said:i have the dcc control module. IS there a way to wire the fan to just turn on whenever i turn the ignition on and turn off when i turn the ignition off?
That wiring diagram... is not the best one to use... you could end up having both speeds on at the same time... not good... heres the proper one to use.mheideman said:Heres a wiring diagram from previous threads:
I have the dcc FK60 unit and havent had any issues with it since I figured out how I want it to work. Look on your installation sheet that came with it, and put the jumper on the controller thats for the underdrive pulley (13 & 14). That will make the fan run at 10% as soon as you turn the ignition on. I ran the yellow (ign wire) into the cab, and tapped it into the cigarette lighter positive. That way, the second I turn of the ignition, the fan goes off as well. I didnt connect the blue (a/c) wire to anything. The a/c compressor has its own fan and intercooler, so its pointless connecting that. I have a picture Ill dig up, showing where to put the jumper in at. Give me a minute.cretamk said:i have the dcc control module. IS there a way to wire the fan to just turn on whenever i turn the ignition on and turn off when i turn the ignition off?
Theres no problem with it. Hooking up the jumper I described on our controllers, only runs the fan at 10% which hardly draws anything. It wont overwork the fan, seings as how the fan is already running. It doesnt have to start and stop, just speed up and slow down based on the temp. Remember, the controllers that cretamk and I have, are a variable speed, not just a high/low setting. Also, theres no reason for his battery to die unless he has the igntion on with the engine off, and lets it sit.HEMI450HP said:Yes, but yo udont want to do that.

cretamk said:thanks mheideman. i hooked it up to 13-14 and it works at 10% when the ignition comes on, but my temp sensor still isnt working. my truck starts to overheat and the fan doesnt turn on at full speed.
Move the sensor away from the direct airflow from the fan, otherwise it could give the controller a false reading. Others who have the same controller as us, have found better luck putting the temp sensor down by the engine inlet instead of up by the outlet. Like I stated earlier, Im happy with mine at the bottom of the radiator on the engine outlet side.cretamk said:the yellow ign wire is hooked up to the cig light fuse. it works fine because it does power up at 10% when i turn the ign on. The temp sensor is on the engine side of the radiator. between the fan and the radiator.
