Porter Cable Router

Well to me its looks like the red and blue wires is going to the square block and that is your DC out +ve and -ve at the other end is mains AC in where it is marked L and N but the earth seems to be connected to the bolt that is going through the centre of the transformer and if here is a metal plate on top it could be causing a shorted turn in the transformer. that needs checking out.

One other point is you need to check if this was wired for 110V or 230V before use and it need a good clean up with new connection block fitted ...Clive

This is not a motor it is a power supply
