Remove the yellow and black wires and move the blue wire to the Low speed Terminal (Marked "L") or the High Speed Terminal (Marked "H").

Disconnect the black wire.
Are you getting 240 volts line to line?
Did you check the resistance of the windings?
Also, check for resistance from each terminal to ground with all wires disconnected.

I get 240 line to line, but the only way I can check it is by disconnecting everything. I can't check it while in service because the breaker trips before I can get test leads on it. I don't know how to check the resistance on the windings.
Disconnect all wires and check ohms from terminal 1 to to 2, 2 to 3, 1 to ground, 2 to ground and 3 to ground.
I think I have a short across the windings.
I'm getting anywhere from 1.5 to 3 ohms with continuity ground to high speed side of board.
I'm getting 1.5 ohms with continuity ground to low speed side.
I'm getting 0 ohms with continuity low speed side to high speed side.
I shouldn't be getting continuity should I?
Post the ohms from
terminal 1 to to 2
2 to 3
1 to 3.
1 to ground
2 to ground
3 to ground.
terminal 1 to to 2
2 to 3
1 to 3.
1 to ground
2 to ground
3 to ground.
Sorry, just realized I did that wrong.
1 to 2 - 1.5 ohms with continuity
1 to 3 - 0 ohms with continuity
2 to 3 - it jumps around between 1.5 to 3 ohms with continuity.
1 to G - 0
2 to G - 0
3 to G - 0
1 to 3 should be the sum of 1 to 2 and 2 to 3.
Double check the numbers.
0 ohms means no resistance or a perfect connection.
"O.L" means no connection or "Open Line".
You were correct. All 3 terminals to ground read 0.L
1 to 2 was 1.5
2 to 3 was 1.5
1 to 3 was 00.0
2 to 3 takes longer to settle at 1.5 for whatever reason.
It looks like 1 and 3 are shorted together for some reason.
That indicates that both windings are being powered at the same time.
You can take the motor apart and try to figure out how the short happened or just get a new motor.

1 to 2 and 2 to 3 should be different and 1 to 3 should be the sum of 1 to 2 and 2 to 3.
So, 1 and 3 must be connected and the readings for resistance are going through both windings at the same time.
