Motor Will Not Run at All
If the motor will not run at all, ma+e the following chec+s-
1. Chec+ that there is power to the receptacle from which the lathe is powered.
2. Chec+ the fuse on the control panel. The re"uired fuse is a 4/amp, fast/acting 4 mm ' 23 mm fuse. !ee Testing the fuse and fuse holder.
5. Chec+ the fuse holder. They are prone to brea+ing.
7. Chec+ the motor brushes to ensure that they are ma+ing good contact with the commutator. In general, this means chec+ing that the caps that secure the brushes are tight.
4. Chec+ all wire terminations inside the electrical bo', especially the slip/on connectors.
6. Chec+ the switches and potentiometer for signs of physical failure. Test them as described below. !ee Component Tests.
. Chec+ the %E!(#Ts on the speed control board. !ee Testing a %E!(#T in circuit.
8. Chec+ the leads on the large power resistor near the center of the speed control board to ensure that a lead has not bro+en. If you find a bro+en lead, repair it with solder. race the resistor by placing a small blob of >T silicone under it.
