DELCO REMY 11SI REPLACING 11SI ALTERNATOR INSTRUCTIONS
[Figure 2] Identify and tag output (B+/Bat) lead and ground lead, if it has one, when removing old 11SI and install them on same
terminals of new alternator. Tighten output terminal nut to 7.5-10.0 Nm (66-88 lb in) and ground terminal nut to 5.0-8.5 Nm (44-75
lb in), if it has a ground lead. DO NOT OVER TIGHTEN OUTPUT TERMINAL NUT! Delco Remy strongly recommends use of a
ground lead. Plug and seat the weather pack connector into voltage regulator opening

DELCO REMY 11SI REPLACING 10SI ALTERNATOR INSTRUCTIONS
[FIGURE 3] Identify and tag the output (B+/BAT) lead, optional ground lead, voltage regulator number one lead AND
optional relay “R”
lead. Note: The old 10SI may not have an “R” terminal or has one that was not used. If it has an “R” terminal, it can be one of two
types. It may be either a pin or blade terminal identified with an “R” on the end frame [See figure 3]. When following steps below, cut
and terminate the wires one at a time to avoid possible reversing:
1. If old 10SI alternator did not have or use a relay “R” terminal, go to step two.
- Cut terminal off the relay lead, identified with an “R” on case and strip insulation about 1/2“. [Figure 1] Insert wire into red bullet
connector from red (shorter) adapter lead, crimp and plug into mating red connector of adapter.
2. Most 10SI’s have a sense lead (connected to # 2 terminal) which is not needed on the 11SI. Therefore, cut the lead and tape it to
prevent it from grounding. It is “live” hot.
3. On vehicle voltage regulator connector harness, cut the wire to number one terminal (“1” identified on end frame) and strip
insulation about 1/2“. [Figure 1] Insert wire into blue bullet connector from blue (longer) adapter lead, crimp and plug into mating
blue connector of adapter. Note: The blue lead must be connected for the 11SI to “turn on” and operate correctly.
4. Plug and seat the weather pack adapter into the alternator regulator opening.
5. If it has a ground lead, place it on ground terminal and tighten nut to 5.0-8.5 Nm (44-75 lb in).Delco Remy strongly recommends
use of a ground lead.
6. Place output lead on output terminal and tighten nut to 7.5-10.0 Nm (66-88 lb in). DO NOT OVER TIGHTEN OUTPUT
