Your'e welcome, I am still 80% electronics at the moment and 20% vacs but need to reverse that figure when i eventually take the leap and work for myself.
If i ever get one in with same fault i will attempt a board repair and document accordingly.
As Dysonboy suggests try to leave an item switched off if it had a meaty reseviour capacitor, to spot them they will say for example 180uf 400v - reason it is 400v is the mains is 230vac but rectified full wave and brought up with the cap it will be around 320v to 340v dc.
Modern power boards will have a resistor across the cap upto 100k usually and this discharges the cap for you when switched off - some equipment doesn't have the resistor and can stay charged for days. I always have a 100ohm resistor to hand with probes on to force discharge or a rather crude method is to use the metal screwdriver over the cap terminals.
The capacitor on a dyson motor for example shouldn't hold a charge after power down as that's a different type of cap. If in doubt check it with a multimeter on dc voltage range.
There are many variants of power supplies, and i still get caught out 33 years later !
Sounds good!
That reminds me, I once had a DC14 witha blown motor, so I unplugged it and I got a shock from the plug touching the prons (literally away from the socket, it still had charge
Didn't you also say that somewhere else on here since I remember reading it somewhere?
I once did that not too long ago, My DC14 funniely enough. has an MTR299 though cause I thought to put my most powerful motor in my best cleaner so? Didn't bother pressing power switch as I was only moving to another plug socket about 5 metres away. Unplugged it and just during spool down (Makes it sound like a turbo
) I grabbed the entire plug.. Yep ive had that feeling too Tayyab
