David P Posted October 4, 2009 Share Posted October 4, 2009 I am fitting electric fans, is there a convenient ignition feed under the bonnet I can use to trigger the relay? Quote Link to comment Share on other sites More sharing options...
Kev.O Posted October 4, 2009 Share Posted October 4, 2009 Surely you'll only want the fans to run at a set temperature? Quote Link to comment Share on other sites More sharing options...
David P Posted October 4, 2009 Author Share Posted October 4, 2009 I have fitted a thermostat, of course, and now want to find a convenient ignition feed under the bonnet. This will prevent the fans from running after the engine is turned off but still hot, and save me having to tear out the dash or stand on my head for an hour to get at the fuse board in the drivers footwell. I have had a probe about, but cannot find an obvious source. Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted October 4, 2009 Share Posted October 4, 2009 Electric fans was one of the mods I regretted, the stock fan system is far more efficient and less troublesome IMO Quote Link to comment Share on other sites More sharing options...
David P Posted October 4, 2009 Author Share Posted October 4, 2009 Mine is N/A, less heat to get rid of. Had electric fans on all cars for last 30 years, no probs. They only come on when you are stuck in traffic, when rolling, then flow of air through the grill is sufficient. But this is getting off topic. Is there an accessory ignition feed lurking somewhere under the bonnet? Anybody! Quote Link to comment Share on other sites More sharing options...
jevansio Posted October 4, 2009 Share Posted October 4, 2009 Maybe pull the plug off something like the ignitor, use a volt-meter to check if any of the pins are ignition Quote Link to comment Share on other sites More sharing options...
Terminator Posted October 5, 2009 Share Posted October 5, 2009 (edited) Electric fans was one of the mods I regretted, the stock fan system is far more efficient and less troublesome IMO Totally agree, waste of money, effort,time for reduced cooling. Another stupid de-clutter mod. But if you must you should take a feed straight from the battery and trigger a relay with a thermostat in the water system. They will still be more restrictive than the stock system. Edited October 5, 2009 by Terminator (see edit history) Quote Link to comment Share on other sites More sharing options...

Must admit, my car runs hotter with the electric fans than it did before with the viscous fan, esp in summer when in stop start traffic .

GazB Posted October 5, 2009 Share Posted October 5, 2009 After ditching the first 2 cheap ebay fans I've not noticed car running hotter with electric fans, did blow a few fuses to start with Patched into ECU so they trigger at set temp. Sounds a bit like concorde taking off I've had to play with map has they wanted to come on just as i get to the burn out point after standing in queue. then stay on for next 12 seconds I'm like others, second time around i would bother changing from viscous Quote Link to comment Share on other sites More sharing options...

Not sure of the colour but should be easy to find. Quote Link to comment Share on other sites More sharing options...
