I think I posted this in the wrong section hence very few responded.. Hopefully this is the right section now.
I have the above speed controller and would like to test if it is functioning the way it should but don't know how to go about it. The Dremel without any doubt overheated in use. After switching it off and resting it for a while, it just would not switch on again. I have also checked the switch which is fine.
I have attached a few photos hoping it will help. Could somebody please tell me how to go about this. I have a decent Fluke meter. The voltage in is 240Vac (UK). The 2 screws are where the 240vac is input. Right hand screw is positive. I checked the diodes on the back of the board and they all seem to be OK. (About 0.7v)
I would really appreciate some ideas on this. Thanks a lot folks.........Take care, stay safe.
