No one can give an exact Ohm reading for you since each laser is calibrated from the factory differently. The only proper way is to hook up the drive to an analog oscilloscope and adjust it so that the voltage levels don't overshoot the eye pattern the system generates.

Otherwise, just fiddle with it until it can read discs again.
