Thanks for the replies.
Would be good to get another set of readings Steve, maybe my meter is out to lunch. Don't worry, if you forget and don't reply I'll probably forget you were going to.
Ground, no had it sitting on the bench. A short to ground could make it draw more I guess but without the ground the draw should be representative.
Thats exactly what it is Terry. Think the same applies with straight blade fans too, used the current draw to fine tune a dust collector system one time. Any pressure drop in the piping would show up as a reduction in current. That one had a 2 hp motor on it. If I get the current draw figured out I'll try reducing the flow to get the electrical draw down, but belt on or off was the same last night.
The two motors I tried are the split phase flavour with no start capacitor, does load not affect current draw at low loads?

Free advice is worth exactly what you payed for it.
