Hi William,

Yup, I checked and it is not actually the motor. Being an older one it
did not have a start-cap but a delay relay in conjunction with the
switch. It is the switch and relay that have burned up. The motor still
runs but in any direction it feels like it. Not good for a sander. grin

HF don't have the switch and relay either as they have no manual and I
have no manual and thus no part number for it.

I can't just add a cap to the motor as there is no centrifugal switch.

OK, the wires are not quit th bunch I thought. After cutting some cable
ties it turns out I have...

Black and Yellow going to the field windings.
Blue and Brown going to the tach windings
Each of the brushes have spade terminals on them and no wires as yet.
