DELCO REMY 11SI REPLACING 12SI ALTERNATOR INSTRUCTIONS
[Figure 4] Identify and tag the output (B+/BAT) lead, optional ground lead, volta ge regulator number one lead and optional relay “R”
lead. Note: The old 12SI may not have an “R” terminal or has one that was not used. It will be identified with an “R” on the case, if it
has one. When following steps below, cut and terminate the wires one at a time to avoid possible reversing:
1.
If old 12SI 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 12SI’s have a sense lead (connected to # 2 terminal) which is not needed on the 11SI. Therefore, cut the lead and tape it to
prev ent 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 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 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 TERMINAL NUT!

DELCO REMY 11SI REPLACING A BOSCH K1 ALTERNATOR
[Figure 5] Identify and tag the output (B+), “D+”, "W” leads, which are identified on the end frame, and optional ground lead when
removing the K1 alternator (Note: The “W” and ground terminals may not have been used). When following replacement steps
below, cut and terminate the wires one at a time to avoid possible reversing.
1. If the Bosch K1 alternator did not have or use a relay “W” terminal, go to step two.
- Cut terminal off the relay lead, identified with a “W” 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. Cut the ring terminal off “D+” lead of vehicle wiring harness and strip the 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.
3. Plug and seat the weather pack adapter into the regulator opening.
4. If a ground lead was used on the K1, place it on the 11SI ground terminal and tighten nut to 5.0-8.5 Nm (44-75 lb in). Delco
Remy strongly recommends use of a ground lead.
5. Place output lead on output terminal and tighten nut to 7.5-10.0 Nm (66-88 lb in). DO NOT OVER TIGHTEN OUTPUT TERMINAL
NUT!
