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.

5.The capacitor is mounted in a molded plas- tic holder. To remove it, pull out on the top of the holder, then slide it upward.

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

7.Loosen the two screws on the top of the capacitor. Leads #202B and #202 (Red) attach to the positive (+) terminal. Leads #201C, 201B and 201A (Black) attach to the negaive (-) terminal.

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.

9.Replace the control panel and tighten the 6 sheet metal screws with the 5/16” nut dri- ver and 5/16” wrench. Replace the top cover of the control box and tighten the 8 sheet metal screws with the 5/16” nut driver.
