At the mens shed we have an older version of this lime green 100 mm belt x 150 mm disc Ryobi sander.
423403
The switch has burnt out and I replaced it with a new No-volt switch but now the sander runs the wrong way.
Apart from earth there are only three wires coming out of the motor one (blue) is a common or neutral, the other two (brown and black) go to the start and run coils.
Normally the way to reverse these is to swap either the leads over on one of either the start or run coil.
To do this I would have to open up the motor and find out where the ends of the start and run coil meet which seems odd because it was running the right way before I changed the switch.
I then went back to the burnt out old old switch and see that it had a small coil inside it which seems to have acted as a monetary connection to the start coil but for the life of me I cannot see how that would change the direction.
Anyone have a clue and does anyone know if parts are available for these machine
