I did some checking. I got a working motor and new cable. The wiring to the motor was correct. I double and tripple checked. I remapped the extruder motor to drive 4, heated up the hot end and manually extruded (without actually extruding just running a motor) and it worked fine. I remaped the same setup to drive 3 (original E0 driver) and the new moto did not work and I got the same warning for a short to ground. So I do have a bad driver for EO on the card. I then Checked the BIQU motor. I have readings directly form the motor. one coil is 2.7ohm and the other is .7ohm. So iI do also have a bad motor. Probably what fried the driver on the Duet. So off to search for anew motor. Looks like the gear on the motor is pressed on and accordingto everything I have found not available. It a NEMA 14 motor but all have a plain shaft. So I will contact Biqu to see if one is available. So I do appreciate the help. It pointed me in the right direction.
