Re: Spectra S1+ Breast pump - No suction
Top of Q9 does not connect to Q7 or any other leads.
Top of R21 connects to the Source pins of Q7
R21 and R30 are in series and bottom of R30 is connected to the Gate of Q7
I’ve attached pics to show the operations of Q9-12 when powered on and off.
Seems like Q9 possibly cycling whatever’s plugged into connector SOL? Looks like maybe an actuator. But that’s the clicking I hear when powered on without suction pump.
