tolerate Posted January 13, 2015 Share Posted January 13, 2015 Hi All, I'd like to buy the fan control resistor for a 77 280z, part number 72 from here http://www.carpartsmanual.com/datsuns30/DatsunZIndex/Electrical/AirConditioner/tabid/1673/Default.aspx Thanks Quote Link to comment Share on other sites More sharing options...
NewZed Posted January 13, 2015 Share Posted January 13, 2015 New ones seem to be available. What does that part do anyway? Quote Link to comment Share on other sites More sharing options...
z240 Posted January 13, 2015 Share Posted January 13, 2015 Motor speed control by increasing resistance hence lowering voltage to slow the motor. The fan switch just controls which of the two resistors are put in series with the motor. One, both or neither. These resistor boards sits in the fan air stream mounted into the top of the fan housing to remove the heat generated by this archaic speed control technique. If you get stuck I have a couple. spalusa.com also lists some 3 and 4 speed resistor packs that go with their fans. BTW, spalUSA also supplies complete new squirrel cage fan units .https://webstore.spalusa.com/en-us/productlist/0141/products/centrifugal-blowers/blowers+single+wheel.aspx I'm sure one of them would be a pretty good replacment instead of doing the honda motor swap. Take some work to adapt one, but still. Just another option. VintageAir uses spal fan motors on their custom A/C units. Quote Link to comment Share on other sites More sharing options...

Hi, would you be willing to sell me one resistor set? its got 3 individual resistors right? Quote Link to comment Share on other sites More sharing options...
chaos Posted January 17, 2015 Share Posted January 17, 2015 I just pulled this from my 72' don't know if it the same but I have a spare one, pm me an offer if it works. Quote Link to comment Share on other sites More sharing options...
z240 Posted January 18, 2015 Share Posted January 18, 2015 Tolerate, send me an email to z240@shaw.ca and I'll show you what I have. They are two resistors. Full speed bypasses them both, then med and low are one or both resistors. Quote Link to comment Share on other sites More sharing options...
