Our Dyson 360 eye has died!
No battery charge light showing when on charge cradle, but I think battery is fully charged anyway.
No response when pressing start button ( except center right led flashes briefly)
Bought new battery just in case but same symptons.
Dismantled unit fully to investigate.
V2 motor has only two wires to it, red and black. black is 0volts from battery, red is battery +Ve but switched via mosfet in battery terminal pcb. it comes live when the start button is pressed. mosfet works as expected ie control signal ( thin orange wire from batt sig connector on main pcb) goes low when button pressed then returns to high battery volts on release. Full battety power to V2 therefore present while button pressed, but V2 motor does not run. So does this confirm that the V2 motor is dead?
Or is there some clever start control to the motor via pulsing the power line?
I thought that there were two modes of operation , quiet or normal, so how does the motor know which mode? it only has two wires to it, the red and black power leads.
How does the pcb know if the motor is running or not? maybe it senses the battery voltage drop?
Main battery volts to pcb via thick orange wire to only establishes when mosfet on terminal pcb is on.
From memory, when the unit was working, the motor did not start up immediately on pressing the start button, but waited a few seconds for checking surroundings etc before starting.
Sorry for long post but cannot work out how V2 is controlled via only two power wires.
Also rather annoyed warranty does not cover this, Tesla Motor drive is warranted for 8 years, and v2 motors are supposed to outlive brushed motors by design.
Image below shows button being pressed and full voltage to V2 motor. Power is supplied via external power supply, but same happens with new battery connected. Motor not running.
