Ah, different forum, different topic, but same thanks again!
Tried with about 26 V, same thing. The fan spins freely. I did just notice that I get the little "ping" when I connect the circuit and sometimes a tiny motion from the fan that in the SSG tells you it's connected okay and the transistor activates. But no joy when I spin the fan up as hard as I like it just freewheels to a stop. Thanks for the once over, mbrownn, makes me more confident to go over things in more detail now I know that's how it should go.
Edit--got it going with different fan with the windings it came with
, looks like the connections in the photo are correct, this thing has some power! Thanks!
