Washing machine motor to lathe

[Gadgeteer]

I can't remember how I acquired this motor, but I'm getting weary of having to reach over my little lathe to spin the pulley in order to get the motor to spin. After opening the case I discovered that the hot lead wire going to the centrifugal switch has long since rusted away. That is, probably, why the washer was trashed, and the motor removed.

Anyway... since I can't find a wiring diagram for it, I'm hoping someone, here, can help me out in determining how to hook a capacitor to the start winding, so it will start and run on application of power. I think I have determined which wires go to the start winding, but am not sure. Photo with measured resistances is posted for info. A schematic drawing will get me to where I want to be. Thanks.

you have to post a picture where D and E come from.

I assume "0" is a no reading ?

Here's the picture... and, yes, "0" is no reading.

this is not going to be easy.

Check you readings see picture.

c=coil

c1 + c2 = total resistance of the two.
your total is not right A,D (6.4 ohms)

If A,D is 6.4 I would assume coils c1, c2 are 3.2 ohms each.

Thanks for responding, GWIZ. I double checked all the resistances, and found them to be true. Son explained a method, using a compass to determine position of coils, so that's next. Have to purchase a compass.

As I try to make sense of the schematic, and, since I assume it's a 2-speed motor, I wonder, if DE is one speed, and AE is the other. That would leave BC as the start winding... maybe, perhaps? I'll keep going, until I solve the riddle.

depending on the mfg
it may be a reversible motor

IF
A-E = 4.8
D-E = 3.1

AD should be 4.8+3.1 = 7.9

not
A-D = 6.4

I agree maybe a two speed motor.
I was trying to see the grouping of the coils but your first picture is dark and your second is slanted

1) see picture, single speed motor.
note how the 4 run coils are grouped and where the 4 start coils are in relation.

Might be simpler to just replace the motor.

I've got a brand new motor, but where's the fun in using that? And, I'm saving it just in case the furnace motor goes to sleep.
