A person can hook up a cooling fan to a battery by connecting the hot or positive lead to the positive side of the battery. The negative lead wire is then connected to the negative side of the battery.
Yeah, you can hook it to the battery. If you do that be sure to hook it to a switch with a nice bright LED or a line that is only active when the key is turned. I made the mistake of not doing that a few years ago and the fan ran until my battery went dry.
previous owner probally hooked the orange wire up to the battery cause it kept blowing the fuse due to short in the wiring system for the fan. hook up a toggle switch inside the car so you can turn the fan on and off at will.
to shut the fans on and off by yourself. remove the connector for the wires at the fan. hook a wire from the positive on fan motor to the inside toggle switch, do not hook to switch yet. run a wire from the positive on battery, hook to battery after hooking up switch. hook up the wires to the switch. then the battery. its up to you if you want to install a 15 amp fuse in line from battery to toggle switch.. you can also get the power from the fuse box instead of the battery. this should work for you. if not you may need to ground the other fan wire.
Hook it up to a solar panel instead !
the cooling fan fusible link comes off the battery cable then goes down to a plug that turns up towards the fan relay and also the alternator.
Hook positive up first, negative last.
It will be mounted up near the battery on the driver side inner fender.
You can jack the car up and then remove the electric power steering fan. With it removed, you can access the starter where you can then hook up jumper cables to charge the battery! Such a silly design huh?
Hook up a battery charger to it.
alot of the time when the censor for the cooling fan dont work,people will hook the fans up direct.Check to see if there are wires coming from the fan to the battery.I hope that helps.Fred
Coolant temperature sensor may be bad and giving false reading the the computer, therby not giving output command to the fan.
Hook it up to a battery.
