Very new to electronics, learning as i go here;
Anyway, the brush motor wasn't spinning,. so i strip the Dyson down seems to be getting power to this little circuit board but not to the motor connected to it.
**broken link removed**
100uF 400v capacitor, GBU807 (Bridge Rectifier) and a resistor (WP4S 1R0 5%), there are some on board resistors on the back too. With my multimeter i tested everything i could, found the resistor was blown, removed from circuit and sure enough no connection was getting through it.
Found what i thought was a replacement one from here:http://cpc.farnell.com/welwyn/wp4s-1rja2/resistor-1r-4-watt-5/dp/RE06394

Soldered it in and built the Dyson back together; Turned it on and was rewarded with a lightning show as electrical arks jumped all over the little circuit board, luckily the dodgy switch on the Dyson turned the thing off almost right away and the components seem to be testing ok.
I just want to know what i did wrong, two theory so far are 1, Wrong resistor. or 2, Motor shorting out. I can test the motor resistance, but not sure what i should be getting from a 240v DC motor. Anyway, could do with some constructive advice here.
thanks
