Powerbot VR2AK9000UG not charging

Re: Powerbot VR2AK9000UG not charging

My 9350's from 12/2016 has a charging dock displaying the same symptoms: Correct DC voltage out of the power supply, but only 7.5v DC out of the exposed +/- charging points.

 

I am taking a look at the circuit but no luck yet. Tired of dumping money into this expensive va uum.

 

Anyone find the solution to this seemingly common problem?

I have the same symtom. 7.6v at Dock charging pins. Did any of you verify if that is what the voltage should be? I would replace the dock if I knew for sure this is the issue but I cannot find the answer.

I am sending mine in for repair. I do not know how long this will take or when I will be able to respond, but when I do I can inform you as to what parts were bad and what the pin voltages are (after the repair).
