PROCEDURE (continued)
8. To reinstall the brush holder
assembly, depress the spring-
loaded brushes into the holder and
slip a suitable non-metallic, fairly
stiff retainer through the slots at
the top and bottom of the holder.
A cable tie works well; see Figure
F.6. This will hold the brushes up
so that you can easily install the
holder.
9. With the needle nose pliers, rein-
stall the red and the black wires to
the appropriate terminals on the
brushes. The red wire is inboard.
10. Slip the holder into position in the
generator end bracket. Be careful
not to loosen the 2 attached wires.
11. Reinstall and tighten the 2 screws
with the 1/4” nut driver.
12. Slowly remove the non-metallic
retainer from the brush holder and
let the brushes snap back against
the slip rings.
13. Check the wire connections or
clearance and tightness.
14. Snap the brush holder cover back
into position.
