PROCEDURE - CAPACITOR REMOVAL AND REPLACE- MENT

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 wrench, remove the 6 screws that hold the control panel in place (2 in the front, 2 in the back, 2 in the bottom). Move the panel aside as far as the leads will allow.

4.Discharge the field capacitor by con- necting the jumper wire clips on the black and the red wire terminals on the top of the capacitor. See Figure F.9 for location. Leave the clips on for at least 5 seconds, then remove.

5.The capacitor is mounted in a mold- ed plastic holder. To remove it, pull out on the top of the holder, then slide it upward.

6.Snap the capacitor out of the assem- bly.

7.Loosen the two screws on the top of the capacitor. Leads 202A and 202 attach to the positive (+) terminal. Leads 201 and 201A attach to the negative (-) terminal.

8.To replace the capacitor, reattach the leads to their respective terminals (202A and 202 to positive (+); 201 and 201A to negative (-) and tighten the screws securely. Snap the capacitor back into the molded plas- tic holder. Replace the control panel and top cover of the control box and tighten down the sheet metal screws with the 5/16” nut driver.
