I did this a while ago and posted pictures of my readings in the "Photos" section of the DML. See "Fan Current" at http://groups.yahoo.com/group/dmcnews/photos/album/946523894/pic/list In short, a fan typically draws about 9.1 - 9.3 amps when running. Starting current is several times that, of course. My measurements have been corroborated by Dave Swingle who has measured a ton of fans and sees all the good ones running in the same range. Of course, a fan with broken blades, bad bearings, shorted windings, or some other problem could draw a lot more. If your fans are drawing in the mentioned range, they are probably in decent shape.
