Ford electric fan

So PO installed an electric fan from a Taurus. Problem is the headlights and front blinkers are wired in the same circuit. No thermo switch either. Fan runs constantly. First-how do I isolate the lights?
Second-where do I get a switch so the fan goes on and off? I already had to get a solenoid for a golf cart that can handle the constant draw from the fan. Sometimes I can tell when the battery is low from on/off cycles due to distributer issues I had because the fan shuts off and the blinkers come on dim. I'm assuming it's due to not enough juice to switch the relay? Maybe. Thanks

 

To straighten out the wiring, I would suggest you use paper and pens and draw out the circuit. If you can't figure it out from that, post the drawing and maybe we can help.

 

From this statement you would have to have your headlights ON before the fan would work. Are you sure you are looking at the correct power source?

 

Okay. I'll explain what I can considering I know nothing about this. The fan dose come on with the ignition. If I've been starting and stopping the engine a lot (which I have to fix my timing issue) there doesn't seem to be enough juice to trigger the relay. Then my blinkers come on dim,my headlights won't work,and all the lights inside (blinker,high beam etc) come on and stay on till I drive it and get some juice flowing from the alternator. There is no thermo switch to the fan. It runs at high speed constantly. This is very confusing to me. Everything else electric works fine. And NO there is no thermo switch to the fan! I'm just worried about overheating. It's a 225 Dauntless

 

And my engine is the 225 Dauntless!

 

Don't know how to post pics. Don't have a PC. Just my phone.

 

The alternator charges fine. Used a meter to check! I would just go back to a regular fan because this isn't a trail jeep or crawler but the jeep has a body lift and I think it would be too low. Only about half would be pulling air through the radiator!!!

 

Funny you say that! Bought a new battery today and replaced the terminal clamps. Same deal!!! Although the old battery was almost shot!

 

What about the body lift and the motor being lower? Won't that make the normal fan not work as it should?

 

IDK. Probably half the fan would be at the radiator. No. I don't have a shroud. The Taurus fan is in its own shroud.

 

It has welded on nerf bars that will not allow me to take the body lift out. Plus the PO has put all kinds of new lines (brake,fuel etc) that would all need replacing. The jeep looks,sounds,and rides awesome. I can go 55 and let go of the week for as long as I want. I want to get a aftermarket temp gauge but the factory fitting looks huge. And mine doesn't work so I have no clue how hot she's actually running.

 

These jeeps are famous for aftermarket add-on's so I have no idea what you have. The 225 v6 usually has an electric temp gauge that uses a pretty small sender. Is your temp gauge in your speedo housing or somewhere else?

 

It's in the speedo. Neither it nor fuel gauge works. I just found a mechanical gauge that has the right fitting. No worries. And I will just carry a couple of gallons of extra gas in case she runs out.
