Guest kc6wfs Posted April 7, 2001 Share Posted April 7, 2001 Hello, Ahhh Spal fans. I has 2 also, a 14" and a 10" running off a 30amp fuse. It's probably pushing it but I have not blown one since installing them 2 or so months ago. I have some pics on my page of the fans if you want to see them. http://www.geocities.com/kc6wfs/240z.html Good luck.

Guest 1z2c Posted April 8, 2001 Share Posted April 8, 2001 My spal fans are 11 inch duals.They are made in a one piece unit.They push 2750 cfm,s.Sounds like the 70 amp relay will work with both fans.I will try it.Thanks for the info Dave!

pparaska Posted April 8, 2001 Share Posted April 8, 2001 If you want them both to come on at the same time (simplest method, probably no need to do anything fancier), then wire them in parallel to the relay. Just run the hot wire from each fan to the same contact on the relay, and a large, fused hot wire to the arm of the relay. Ground both fans at a good ground and you're set. ------------------ Pete Paraska - 73 540Z - Marathon Z Project pparaska@home.com Pete's V8 Datsun 240Z Pages Quote Link to comment Share on other sites More sharing options...
