What about wht to wht/orn on the motor? (extra low speed)
When agitation stops, does the motor attempt to start in drain mode? Does the timer continue to move?
Assuming the lid switch is good, if the motor doesn't attempt to start for drain, I think you have a bad timer.
The low reading on the low speed winding does indicate a problem however, the motor always starts in high speed regardless if it's agitate, drain, spin, or selected speed via the speed switch. Drain in normally in high speed only anyway.
A clear picture of the wiring diagram and timer chart is needed to help you troubleshoot with multimeter. The different models have variations in the way they are wired.
