Hi i have a weird problem going on with my electric fan. My fan use to kick on at certain temps and stay on until it reached the set temp from the temp sensor, but lately it was kicking on and then going right off after it ran for about 3-5 seconds. So i tested it out and the fan kicks on and the relay is working properly ( i even changed it just in case ) but what i hear that is going on is when it kicks off theres a click which sounds like its clicking in the voltage regulator> So basically i grounded the temp sensor the relay clicks the fan goes on then 3 seconds later there is a click coming from the voltage regulator and the fan goes off and if i try to jump it again right away it wont go back on but i hear the relay clicking on but if i waite about 10 seconds it will come on but only for 3 or 5 seconds or so but then the same thing. Can anybody please help me this is driving me crazy cant figure it out

What type of fan and controller is it? Maybe it has a built in circuit breaker that is reseting? Not sure what you are referring to as the "voltage regulator". Do you have some type of smart controller that does soft starting or something? Try bypassing any controllers/relays and jumpering the fan directly to the battery with some decent sized wire and see if it runs good (don't "attach" it to the battery, just hold the + wire on the + terminal for a few seconds or so).

the fan works . I tested it that way that u just described i dont have a controller just a relay with a temp sensor tested everything relay all is working but what i mean by voltage regulator is exactly that the voltage regulator that is right by the car battery

[87superduperstang]

I might be wrong about the part im describing as a voltage regulator but it is the part that is by the battery that looks like it has 6 or 7 wires going into it like ground and power wires ( i know im and idiot )

That is the starting solenoid..

One of the posts from the solenoid runs directly to the + term on the battery. Electrically, they are the same exact point with nothing but the big + battery wire between them. That post is just a tie point for all things + in the car. If the fan works fine attached directly to the battery, it should work exactly the same when attached to that post on the solenoid (the one with 6 or 7 wires on it). With just that and assuming everything else in the car works fine, I would say maybe your wire running to the solenoid from the fan is a little corroded or not making good contact or bent a little funny or the solenoid post is corroded. But.... If you are hearing the solenoid clicking or making noise at any time other than when you are turning the key to the start position, something else is going on there more than just your fan not working. That is a separate issue that can not be explained with the only symptom being the fan not working.

Can you post some pics or maybe a diagram of how your relay and temperature sensor is wired into the fan?

could there be a problem with the starter solenoid . It is strange because you hear the click in the starter solenoid when the fan is on for like 5 seconds then the fan goes of .Could i just fun the ground and power wire coming from the relay straight to the battery and what about if i temperary run a manual switch what would be the best way to do that without a relay .

[87superduperstang]

found out what was going on. After checking all the wires and tracing back were they all routed to the clicking sound was coming from a start top breaker that the power wire goes into first then to the starter soleniod. I think what is going on is my fan is shorting or grounding out causing it to click the breaker. I tried wiring in a 30 amp fuse in place of the start stop breaker and the fuse blew after about 5 minutes so i thinks it is the fan itself which is a lincoln mark vii fan. So now im actually debating on putting a brand new stock fan in and ditch the electric

lincoln mark vii fans pull a shit load of amps at start up... most people run either an 80 amp relay or a electronic efan controller that slowly ramps power to the fan as needed so it doesn't have the intial 120 amp start up spike.

that fan is probably the best at cooling being rated at 5000cfm but you have to have 8 gauge wiring and either the controller or relay to use it or else you'll melt shit or destroy your alt/battery quickly.

Good thing it at least had that circuit breaker on there or else you'd be looking at smoke.

As fans get older and wear out, they can draw a lot more power. You can get suggestions from others on a decent low power fan from Ebay or something or get a flex-a-lite kit that draws under 20 amps.
This is not directed specifically to anyone but many people use the Taurus and Mark fan because they are plentiful and cheap but they often do not consider the extra wiring, temperature probes, switches, current, battery, charging system, and detail they require to work reliably and safely. Cheap initial cost but you can pay a lot in time and money to keep it going.

[force-fed-snake]

99-04 style dual fans? why dont you see many people running them, everybody tends to lean toward the taurus and lincoln set-ups.... and im just curious if there is a legit reasoning to it.

My electric fan has a switch and today for somereason it wont come on. I hear the same clicking noise when i turn it on but it doesnt move.
