120V AC motor wiring

Hi:
I'm hoping one of you folks can help me here. I have a project that requires a pretty beefy 120V electric motor. As luck would have it, I have a friends spa motor we replaced a few years ago kicking around my garage. I took off the pump portion of it and have what I need motor wise now (has a threaded shaft at the end BUT I forgot how it's wired.

1) This motor has 2 terminals on it: H, C, and L.

2) I cut a PC power cord and came up with 3 wires: black, white, and green.

I'm a neophyte when it comes to AC wiring so please educate me. Which color goes to what terminal?


Thanks,
-gunn


PS. Nevermind. I called a spa place and they explained it to me
H = high speed = black wire for low speed
C = neutral = white wire
L = low speed = black wire for low speed
Ground = goes to terminal on body.

This probably explains why I tripped a breaker when I put black to H, white to C, and green/ground to L.
MODS: feel free to delete this thread if so desired

The terminal syntax is High, Low, Common Ground.

Those are usually pretty beefy motors, use 14 or 12 awg cords.

Sometimes on <1A fan-type motors it will be Hot, Capacitor, Neutral, Ground.

Well, I got it working. It's a testbed for a project i'm planning for my 0HP engine mod for my next lemons race.
Next step is to figure out how to attach a pulley/wheel to the end (as if it was say a tbird belt drive accessory).
