PROCEDURE

1.Remove the engine spark plug wire.

2.With the 5/16” nut driver, remove the 8 sheet metal screws that hold the top cover to the control box. Remove the top cover.

3.With the 5/16” nut driver and 5/16” wrench, remove the 6 screws that hold the control panel in place. Move the panel aside as far as the leads will allow.

4.Discharge the field capacitor by connecting the jumper wire clips on the black and the red wire terminals on the top of the capac- itor. See Figure F.16. Leave the clips on for at least 5 seconds, then remove.

6.Cut the tie wrap and snap the capacitor out of the assembly.

8.To replace the capacitor, reattach the leads to their respective terminals [202 and 202B Red to positive (+); 201C, 201B and 201A Black to negative (-)] and tighten the screws securely. Snap the capacitor back into the molded plastic holder and slide the holder back into position in the panel. Replace the tie wrap.
