Can you just wire and electic fan to a switch and have it on high the whole time?

 

my efan controller died and i tapped my on lead to the fuel pump relay so as soon as i turn my key in the on position the fan is on...im running a 100amp continuous duty solenoid to power the fan..

 

depending on the fan you got and the amperage it pulls you will want to have a relay inline before the switch..if it pulls the power mine does i would recommend the continuous duty solenoid..

 

Hey guys, new to the forum. I recently got a TAURUS EFAN, the single one, and I am wondering how to wire it using a continous duty solenoid. I have found out which wire is for high speed on the fan and I need to know how to wire it. The solenoid has 4 posts on it, 2 large and 2 small. I was told that One of the big posts will go to the high speed fan wire, the other big post is wired to the battery positive terminal. One of the small posts goes to the battery negative terminal and the other goes to an Ignition enabled fuse or relay. Is this correct?

 

correct

 

I am having a problem when I wire or tap into a power on ignition fuse or relay. It seems that everything in the power distrubition box is LIVE with 12 volts. I check them with the volt meter and the key off and they mark 12 volts. Does anyone know which Wire i can tap into that isn't live without the key and gets hot when the key turns forward. I have tried tapping into the IP/FUSE PANEL as well as the ignition/starter fuse. Both are 50 AMP Maxi Fuses. I know one side of their links isn't HOT..I put the ignition wire into this one but as soon as I put in the FUSE over the wire to test this, the fan comes on...even when the key is not even in the ignition. Any ideas where else I can tap into?

 

Can anyone tell me how SteveOh managed to do this? I am at a loss, Im frustrated from messing with this thing, trying to get it to work. I've blown the PCM fuse and the fuel pump fuse several times. I am not sure i'm tapping into the correct wire. Last time I did, the truck and fan ran for 30 minutes then suddenly died...well the pcm fuse blew and the fuel pump fuse as well....I replaced these and the truck turns back on again. I need to tap into something reliable..also using the 100 amp continuous duty solenoid.
