OUTPUT RECTIFIER BRIDGE REMOVAL

AND REPLACEMENT

(continued)

FIGURE F.14 - OUTPUT RECTIFIER CONNECTIONS

PROCEDURE

1.  Perform this procedure with the engine OFF.

2.  With the 5/16” and 3/8” nut drivers, remove

the sheet metal screws from the left and right
case sides.

3.   Carefully remove the left and right case

sides.  Note that the output rectifier is di-
vided into two parts.  The positive portion is
located on the lower right side and the neg-
ative portion on the lower left side of the
machine.

For the remaining steps refer to FIgure F.14.

4.  With the 1/2” wrench, remove the diode pig-

tails and heavy leads from the terminal studs.
Note lead and washer placement: nut, split
washer, flat washer, leads.  Label leads for
reassembly.  See wiring diagram.

5.  With the 1/2” wrench, remove the two heavy

leads and one small lead from the rectifier
heat sink plate.  (Note that the small lead is
always on top for reassembly.)

6.  With the 7/16” wrench, remove the nut and

washers holding the top stud assembly to the
rectifier mounting bolts.

7.  With the 7/16” wrench, remove the nuts, lock

washers, and flat washers from the two top
mounting bolts.  (Note insulator place-
ment.)

8.  With the 3/8” nut driver, remove the two bot-

tom mounting sheet metal screws.  (Note
insulator placement - upon reassembly the
heat sink must be electrically insulated from
the frame of the Ranger 10-LX.)
