Another Unusual happenstance, this 4 wire GE hooked up to a switch with speed coil. 2 wires were together, the last 2 served as power leads. The 2 used as power leads have Ohms readings of 19.8, the other 2 are dead so operates connected... either way. I've never found a healthy 4 wire motor, they do not use a speed coil, motor has 2 independent coils, not connected as like 3 wire motors where the start/run coils I think phase-shift and coils are connected. Low speed-High speeds readings go between .71a 75w to .84a 85w, small amount of heat, I did not check rpms but appeared to me ''normal' for GEs bearing in mind I don't usually mess with GEs. Any thoughts? Probably going to get a re-wind but find this an interesting hook -up

I have run across several 4 wire but only one still working  . Your correct in that they don't have a speed coil , its one stator wire with 4 taps giving it 3 speeds. Seems like a simple design and easy to wind but they seem to burn up easier . I have run across two with 4 wire head wire that had two abandon wires at the motor and in the base . My guess is they didn't throw away anything and used the wire for several model types. I would say yours is a two wire with the other two unused . Just my opinion Pete

Thank you Russ and Peter very much, I think I got it now. I have not removed the motor or case half but peered inside with a flashlight. What I have here is a shaded f 4 pole motor, not the big double loop installed in a double 'S" pattern in the stator laminates. The other 2 wires are not going to be hooked up to any motor wires is my guess, That GE used 4 wire headwire stock utilizing only 2.  I havn't been inside a GE in years but the more I think about it the more I realize I have been here before with Rick Huckabee. I'm SURE I got it now! Thank you again guys! Carl
