Hello,
My Bennett 740 is giving me multiplexer error. 7189. I checked everything BBU, pressure controller board. These are ok. But the Controller board is probably broken. It says that 5V from BBU is too low, so probably multiplexer is broken. Can anyone help me with this?
the error code 7189 says to replace the pressure solenoid. You can donw load the manuals from Medwrench.com. Free access you just have to sign up, say cbet_us@yahoo.com referred
