However, the unlock function only works when the turntable is turning clockwise. If you go counterclockwise it won't unlock and stops at the next track. Any ideas?

The feeler - when detecting a track position (real one or a possible one) - the latch switches off the motor and blocks it so that there is no "overshoot" (using a clutch) If the voltage is too high or if the feeler guide is dry / dirty / needs a little lubrication then it can get stuck and the solenoid is not strong enough to disengage it So 1 check with a lower voltage 12 to 14 VAC, otherwise remove the bridge and clean the motor unit. Cheers Jean
