Having an issue with my parents Bruno Lift Chair. It’s currently working ok except for an error code (see below). I have checked the batteries they are both around 12.6V. Seat switch is disengaged. Voltage on rail is jumpy from 25-28VDC. I’m wondering if the circuit board inside unit is defective.
Thoughts, or anybody seen this??
Parked position with charge not detected: 5 Beeps (3 short and 2 long) Repeats every 4 minutes until the seat safety switch is disengaged, the battery voltage increases, or the switch is pressed
