Starter/Generator Assembly
1. Place the field coil into the housing. The two insulators that look alike fit into the slots next to the F1 and
F2 markings on the outside of the housing. The insulator that looks different slides into the slot next to
the DF marking.
2. After the insulators are seated in the slots, install the threaded terminals through the wire connectors and
then through the insulators. Install a flat washer, lock washer and nut onto each threaded terminal on the
outside of the housing. Tighten nuts to 47.5 in-lb (5.4 N·m) (Figure 12-11, Page 12-6). See following
CAUTION.
