OUTPUT RECTIFIER BRIDGE REMOVAL AND REPLACEMENT (continued)
Reassembly:
Refer to the Wiring Diagram for proper connec-
tions to the positive and negative sides of the
rectifier assembly. The two sides of the bridge
are marked + and –, respectively.
NOTE: Use Penetrox A-13 on aluminum elec-
trical connection surfaces.
10. With the 3/8" nut driver, install the two
bottom mounting screws. Note the place-
ment of the nylon insulators. These must
be in place when you install the rectifi-
er bridge assembly in order to electri-
cally insulate the bridge from the frame.
11. With the 7/16" wrench, install the washers
and nuts to hold the top stud assembly to
the rectifier mounting bolts. Install insula-
tors as previously removed.
