repaired... the actaul encoder motor itself is fine .but the the
plastic part that bolts onto the motor is corroted and it pulled away
from motor about 1/4" which pulls the halleffect awahy from spline so
computer cannot see what poaition it is in , so it defaulted back to
last setting. so the new encoder motor assembly repaired it
thanks
