There's really no reason to keep debating this - you really need to just send it back to Neu. They're a great company and aren't there to rip you off. If they over-tinned the wires and that caused the motor to fail then they'll tell you that. Should have a good turn around time too since they're here in the U.S. Be happy you have a Neu as some of us have learned costly lessons with Lehner motors
