I'm trying to fault find one of these. The old motor did not work when I applied a DC voltage. There was 240AC coming out the terminals of the Dyson with the Head removed, so all switches are working.
I have a new motor which I've just fitted and it still didnt work. I removed the new motor again and tested with a DC voltage, it began to spin slowly, so new motor is OK.
It look like the PCB, but I can't see any obvious faults with the PCB. The motor is 24DC isn't it?
If I connect the head so I can access the brush bar motor terminals, I should get 24DC at the PCB output terminals ?
Is that correct ?
