Hi All,

Finally back into the restoration.

I bought an expensive 5uF capacitor, and connected it directly to either of the input rails to the motor, and its STILL DEAD !

1) There is about 127vAC between the main two input leads.

2) I connected one end of the new 5uF cap to what i think is the middle wire of the motor, and the other end of the cap, to EITHER of the power input wires, but its STILL DEAD.

3) measured voltage between input and the middle motor lead is 6vAC.

4) I measured the resistance between the middle wire and one motor wire, and it is about 80ohms. Between the middle wire and the other motor wire, its about 26 ohms. IS THIS NORMAL ?

I have spent about 5 weekends rebuilding the electronics and its working perfect, it just needs to start spinning !!

The motor number is 7882-032. What is the chances of getting another motor ? Hoping to be able to remove the motor without splitting the chassis, is this possible ?

Any suggestions appreciated.

David
