37 Pontiac SilverStreak Posted March 18, 2013 Share Posted March 18, 2013 Team,I am starting a restoration an a electrical part, being new to this world, I thought I would ask my forum before I tinker... In addition, I was wondering if someone could identify the original colour of the unit...question 1regarding the following fan component, how do I test it... Is the long wire the positive that would go to a switch? And the short the negative? I would hate to test it on a battery the wrong way and blow a 76 year old fan.... question 2regarding the colours, the outside has never been touched, and is original, but it looks like the inside was painted, is there any way to verify its original colour for GM?thanks in advance as always, the forum members are life saves and I appreciate all your help!

Coley Posted March 18, 2013 Share Posted March 18, 2013 You are probably correct in your wire id. It actually won't matter which way you hook them up as long as it off the vehicle.The color may be original although I don't know why they would choose that color.Others will chime in soon.

Rusty_OToole Posted March 18, 2013 Share Posted March 18, 2013 Most likely a 2 speed fan. One wire is low speed, the other hi speed. Ground through the body of the motor. Is there a switch? Is it 2 speed?If it is 2 speed connecting both wires to a battery will cause a spark but not hurt the motor if you don't leave it on. You might want to check with an ohm meter first. If both wires = 0 ohms, 1 wire to ground, 5 ohms, other wire to ground, 10 ohms, or something like that, my guess is right. If both wires = 5 homes, 1 wire to ground, infinite, other wire to ground, infinite, then your guess is right. Link to comment Share on other sites More sharing options...
37 Pontiac SilverStreak Posted March 19, 2013 Author Share Posted March 19, 2013 Thanks Rusty,there is no switch, all there was, a motor w/ fan bolted to the middle of the coils. Sort of like a small round radiator.very easy to pull apart to clean and paint, inspecting the actual motor part, all it has is a long wire, a short wire attached to the shell, and a second screw that is all by itself...i am unsure about speeds, I think it's just one speed, to blow the heat away from the coils and into the car... Ill get the meter on it to check... Link to comment Share on other sites More sharing options...
Seldenguy Posted March 19, 2013 Share Posted March 19, 2013 I am quite sure it is a one speed motor when hooked direct to supply. Most such applications then used a combination varible rheostat/on/off switch under the dash to control the speed of the blower motor.

37 Pontiac SilverStreak Posted April 28, 2013 Author Share Posted April 28, 2013 Anyone know where I can get a new motor . Upon inspection, the wires are too old, word and while testing unit separately, I see sparks where there should not be... Safer to replace then to restore...its a 3 inch diameter wide, I saw something similar on one of the summit racing websites for around 45$.thanks Link to comment Share on other sites More sharing options...
Seldenguy Posted April 28, 2013 Share Posted April 28, 2013 Trevor, take the two bolts out, carefully separate the two halves feeding the wires through the holes. They will now be exposed to the internal connections. Unsolder these bad wires, replace them with new and like sizes. Reassemble and I would be surprised if it did not work. Most these motors seldom ever burn out the stator or rotor windings, if it still does not work then you do need a replacement. Also oil that little felt dust seal that the shaft runs through. The rewiring should only take you 30 minutes and if the motor runs you have saved $45 + shipping. Good luck in your efforts and let us know if you fixed it or had to purchase one. --Bob Link to comment Share on other sites More sharing options...

Rusty_OToole Posted May 4, 2013 Share Posted May 4, 2013 When it is apart can you see where the wires go? This may tell you if it is 2 speed or not. Link to comment Share on other sites More sharing options...
1fun37 Posted May 11, 2013 Share Posted May 11, 2013 I agree with Bob, replace the wires. One goes to the motor to ground it and the other to 6V power, it is not a 2-speed fan motor( by your picture). If you have converted to 12V you may need a 12V motor as the original 6V will turn very fast. I just did one on a 1937 Chevy pickup, same motor, same problem.

37 Pontiac SilverStreak Posted May 14, 2013 Author Share Posted May 14, 2013 Sad news, this motor cannot be saved, just far too gone, 5 motor shops said they could try and recover it, but best to just get a new motor.... They run about $60... Labour would defeat its purpose and even then no guarantee anyone have an idea a brand to use? Link to comment Share on other sites More sharing options...
37 Pontiac SilverStreak Posted May 15, 2013 Author Share Posted May 15, 2013 Thanks everyone... The Filling Station has my parts.. Both 6 and 12 volt...this post has been resolved .now to choose some colours Link to comment Share on other sites More sharing options...
