Apply 12 volts directly to the motor terminals (reverse polarity for opposite direction). The motor (actuator) rod should finish its travel in less than one second.

Using Rotunda Digital Volt-Ohmmeter 007-00001 or equivalent, the motor current draw (stall test), should not exceed 6 amps. Reverse the polarity to the connector and retest.
