jpk Posted August 29, 2006 Share Posted August 29, 2006 Evening all. I have acquired a mondeo twin fan setup for my 200tdi. I know a few people have used this setup before and was wondering if you could advise me on the best way to wire it all up without melting anything. Both the motors have a 3-prong plug and there is what appears to be a resistor in the one corner with its own plug? My auto electric skills are a bit dodge so any help gratefully received. Thank you all JP Quote Link to comment Share on other sites More sharing options...
JST Posted August 29, 2006 Share Posted August 29, 2006 tried the tech archive? Quote Link to comment Share on other sites More sharing options...
Mark90 Posted August 29, 2006 Share Posted August 29, 2006 I've got twin mondeo fans on my 90, binned the "resistor in the one corner with its own plug" and the motors just had two blade connectors on each one, trial and error gets the fans going the right way Quote Link to comment Share on other sites More sharing options...
jpk Posted August 29, 2006 Author Share Posted August 29, 2006 Thank you for your replies. I tried the search option but had no joy on specific wiring solutions. I was mainly curious as to what the function of that coil in the corner was. Also, Mark90, have you had any problems with them fitted? Do you have them both cutting in together or dependant on temp? Again, thank you for your help. JP Quote Link to comment Share on other sites More sharing options...
Mark90 Posted August 29, 2006 Share Posted August 29, 2006 No problems at all with them. Have them switched to come on at different temperatures using an X-Switch (which BTW gets a thumbs up from me) and the high temp fan has never come on, the low temp fan always provides enough cooling and that's with hard off roading a 4.2 V8, might need both fans if the rad gets blocked with mud etc. Quote Link to comment Share on other sites More sharing options...
jpk Posted August 30, 2006 Author Share Posted August 30, 2006 Thanks for that. I was planning on using the X-eng switch as well so I'll give it a go. If you smell something burning it's probably just me getting it slightly wrong. Quote Link to comment Share on other sites More sharing options...
JSG Posted August 30, 2006 Share Posted August 30, 2006 Mark, I assume you've got the fans wired with a relay between the switch and the motor? Quote Link to comment Share on other sites More sharing options...
Mark90 Posted August 31, 2006 Share Posted August 31, 2006 Yep wired through relays, however not strictly necessary unless you have very high powered fans as IIRC the intermotor switches are rated to 17A, but relays are best IMHO. Quote Link to comment Share on other sites More sharing options...
