REMOVAL AND REPLACEMENT (continued)

PROCEDURE - CAPACITOR REMOVAL
AND REPLACEMENT

1. Remove the engine spark plug wire.

2. With the 3/8” nut driver, remove the 4 sheet

metal screws that hold the top cover to the con-
trol box. Remove the top cover.

3. Discharge the field capacitor by connecting the

jumper wire clips on the black and the red wire
terminals on the top of the capacitor. See
Figure F.12 for location. Leave the clips on for
at least 5 seconds, then remove.

4. Both the capacitor and the diode bridge are

mounted in a molded plastic holder. To remove
it, pull out on the top of the holder, then slide it
upward.

5. Snap the capacitor out of the assembly.

6. Loosen the two screws on the top of the capac-

itor. Lead 202A (Red) attaches to the positive
(+) terminal. Leads 201 and 201A (both Black)
attach to the negative (-) terminal.

7. To replace the capacitor, reattach the leads to

their respective terminals (202A Red to positive
(+); 201 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 top cover of the control box and
