Electric radiator fan issues

[JJ240]

Anybody else ever had issues with electric fans causing interference that screws with the engine? I've got an SR and even if I hook the fans up to a battery sitting on the ground outside the car it still causes it to idle rough and even die sometimes. It must be some sort of EMF screwing with some signal...I think its the CAS, but I've aluminum taped the CAS wiring and it still does it. I'm out of ideas, and don't have a clutch fan and shroud. Anybody else think of anything?

you should try to get a video of this and post it on youtube or some crap and give a link, because thats just frickin crazyness.

i have the same problem but i wont worry too much....my car never died on me hehehe lucky me. its like its robbing power from the battery.....not sure but my e-fan is hardwire with switch with 20amp fuse on it. about to check my alternator if i were u guys if its outputing the correct voltage

it;s doing that because you don;t have a relay installed. I have one in my RB and i have never stalled / idled low.

install a rellay and call it a day. sooo.....


SEARCH NOOB!!!!

yes relay could be it ^I'm with you juan

ya get a relay. i had the same prob. fixed it in a jiff.

[JJ240]

why would a relay make a bit of difference...did you read my post? It would have taken you less time to read the damn post and realize I said I powered it with a battery that WASNT EVEN ATTATCHED TO MY CAR than it took to set that up in giant red font.

edit: its EMF from the electric motor that is causing it...you can pull the fan away from the engine and it works fine, then when you set it in place behind the radiator it screws with the idle.
