Got voltage from the control unit. Call the supplier they are sending me a new regulator. Will post after installing it.
Thanks again for your help!

New resistor didn't work

Control module voltage,
Lowest speed, 2.84V
highest, 10.11V
The only difference of the resistor is these #
Original V7191003
New, V7191004
