Check the small wire on the starter solenoid. It is likely mispositioned and is touching the large terminal with the battery cable attached to it. If that is not the case, disconnect that smaller wire from the solenoid. If the starter still engages when you connect the battery cable, the plunger with contact disc is stuck inside the solenoid. Have the new starter replaced under warranty.
