Could be a defective starter - sounds like the solenoid is stuck on the new starter, or it was wired in wrong. There should only be 12v on the small post of the solenoid when the key is in the crank position. If it has 12v all the time, this will happen. Another possibility is a short to power on the "crank" signal wire.
