When you were checking for power, when you shut the switch off, did it shut the power at the connector? Also, when you were checking power to the connector, was there a drop in voltage when the switch was changed from hi to low speed? If both of these things occurred, the switch is good. What I would try is to ground the new motor and try it again. That is most likely your problem.
