i have it in but can't find a power source to hook it up to. I don't want to run a thermostat i just want it to come on when i turn the key. Any ideas



Thanks fopr all your help

put it on a circuit that is only on with the ignition

 

Make sure you use a relay w/ power from the battery. Don't just rely on any 12 volt wire you can find. Do a search in this forum, there are quite a few threads on the topic and lots information. Should be an easy install and will be headache free if you do it right the first time.

 

sorry guys i totaly forgot to search, i really don't like kicking dead horses

 

I've used the alt wire in the past...

 

You really don't want to do that....... Having it run all the time defeates the purpose of an e-fan and will put a constant load on your battery or charginf system. If you still have a stock alternator, you may find that your battery will die if you do a lot of stop and go driving.

Plus, you will burn up the e-fan real quick by running it all the time, they are not designed for it.

BUT, If you MUST... get at least a 30 amp relay and wire it into the postive line from the battery. hook the switch post of the relay up to a wire tapped into a ignition circuit... I think the little green wire over by the pressure sensor with a flat connector has 12v on ignition but its been a long time

 

This is going to turn into ANOTHER e-fan all the time/ some of the time / WHY are you going efan anyways thread..........(puts on kelwool suit.....)

 

A fixed thermostat & a relay come to about $25.

I wired NA's fan relay to the battery by way of a 20Amp breaker.

The longest it would stay on after I turned off the key was 15 seconds.

(The NA equivalant of a turbo timer)

 

My fan relay gets fan power direct from the battery, and the relay switching power comes from the optional E-fan wire installed on the TII. Then its all controlled by a thermostatic switch.

This way if I shut the car off, the E-fan shuts off too.

Do it right!

thanks alot guys. aaron cake someone from kcrx7club gave me the same link

My stock fan went out today and since my seven is my daily driver i could not wait to find a new one or let it over heat.

Also, sorry for not using the search button

 

Is it bad to leave the efan running the whole time your car is on?

 

It totally defeats the point of having an electric fan, it consumes more power than the stock fan, it puts a constant high load on the electrical system, it shortens the life of the fan, and it hinders airflow through the radiator at high speed. You tell me if it's bad...

 

NZConvertible, I have come to the conclusion; Running the Efan the whole time the car is on, is a BAD idea.
