add some images showing us where you are measuring. The DC output on your power supply should be between 21V and 24V. Your battery voltage should be between 15.5V and 18V. This could be an issue with the power supply.

I am getting also 2 DC Volts between docking terminals. The battery charges properly with a DC 21V power supply directly connected to the robot.

Any docking repair guide available?
