SOMETHING VERY INTERESTING.

This attached photo is from a TK60. The motor looks identical to my TK64 motor. It has the 3 terminals on the back of the motor.

The photo from the TK60 service manual, shows there is NOTHING connected to the 3rd terminal. But in my TK64 there is (what i am assuming) is the center tap of the motor, which i am connecting to the capacitor and its not doing anything.

As i mentioned previously, if the 50/60hz switch is set to the 60hz position, the (what i assume is the motor middle wire) is OPEN and not connected to anything.

I have assumed the 3 wires and tags on the back of the motor are, 2x for power in and one being the centre tap.

I cant find a schematic for a TK64 with 50/60hz switching and TWO motor capacitors sandwiched between the chassis and electronics.
