1. Remove alternator cover and existing voltage
regulator. Also remove heat sink from front of
alternator.
2. From rear of alternator, feed non-crimped end of
new green wire through slot near R terminal on
new regulator.
„
A1-165 and N1088 — green jumper wire
is not required. Connect black E lead from
shell E terminal to R terminal of new regula-
tor. Y terminal connection is not used.
3. Cut wire to proper length. Install sleeve, strip
wire, then crimp and solder larger terminal to
end of wire.
4. Re-install heat sink, connect new green wire
to phase terminal closest to output terminal. Do
not attach this wire to phase terminal with more
than two wires already attached.
5. Install new regulator on alternator and finish
wiring as shown in Figure 1.
6. At rear of alternator, attach new green wire to
back of R terminal.
7. On INSIDE of alternator cover, use supplied
template (II0005A) to cut new opening in cover:
a) Drill 1/8” pilot hole, then 9/16” hole.
b) Deburr new hole to prevent damaging
new switch on new circuit board.
8. Re-install alternator cover.
