6. Cut lead assembly to the length determined in Step 5. Mark ferrule on spark plug end of lead with
a metal stamp, scribe or rubber stamp to correspond with correct cylinder number.
7. Starting at spark plug location, thread new cable through grommets and clamps as necessary for
correct routing of cut end of cable to magneto location.
8. Using electrician’s scissors, carefully remove 1.250 inch of outer braid from end of lead. (Refer to
CAUTION
Use care not to nick or cut insulation when removing braid.
9. Using a scribe or similar pointed tool, unbraid 3/8 inch of braided shielding. (Refer to Figure 8A-
21.) Wrap a single thickness of electrical tape around unbraided strands to facilitate insertion of
lead end through hole in cable outlet plate.
10. Remove cable outlet plate from magneto. Support plate securely and, using suitable cutting pliers,
split and remove eyelets from leads adjacent to lead being replaced. When splitting eyelet make
certain that wire strands are not cut. Removal of eyelets on adjacent leads will allow grommet to
be pulled away from outlet plate to facilitate insertion of new lead.
11. Pass the taped end of new lead through hole in outlet plate. Remove electrical tape from lead and
install tapered end of ferrule under the unbraided strands of shielding. Form strands of shielding
evenly as shown in Figure 8A-22 and pull lead assembly back through cable outlet plate until
ferrule binds in the outlet well. Position the Scintilla 11-7074 Ferrule Seating Tool (Figure 8A-23)
over the wire and firmly seat the ferrule by tapping the seating tool with a hammer or by using an
arbor press.
12. Measure 1/2 inch from tapered ferrule and strip remaining insulation from wire. (Refer to Figure
13. Insert Scintilla 11-7073 Needle (Figure 8A-24) through small hole of grommet and over stripped
end of wire. (Refer to Figure 8A-26.) Slide grommet down needle until it seats tightly against the
tapered ferrule.
14. Cut wire 3/8 inch from top of grommet outlet. (Refer to Figure 8A-27.) Double wire over as
shown in A of Figure 8A-28. Slide eyelet over doubled wire until it is firmly seated in recess of
grommet outlet.
15. Using the “AB” groove of Scintilla 114152 Crimping Tool, or equivalent, crimp eyelet to wire.
Approximately 1/32 of an inch of wire should extend from end of eyelet after crimping. (Refer to
B of Figure 8A-28.)
NOTE
If the crimping tool is not available, a satisfactory connection can be made
by soldering with Kester Flux 709 or equivalent and a non-corrosive solder.
After soldering, clean solder joints using denatured alcohol.
16. Install clamps and cable ties as necessary to secure lead to the engine.
