Looking for schematics to patient lifter, model SARA 3000.
Also suggestions why lift motor would work one way but not the other. To be more specific, if the power wires are connected to the the motor in such a way where the shaft can be extended, it will not retract. To make it retract, requires reversing the power wires and vice versa. Have checked toggle switch, and handset buttons, no problems.
There are a total of 8 mosfets on the main board, all type IRLZ44N. The base leg motor works ok but not the lift motor. All mosfets check out ok.
