Gm 10si Alternator Wiring Diagram. The GM alternator used in all Chevrolet models is easy to install as it is connected using only a few wires. The alternator converts the engines mechanical rotations into an electrical current using a pulley-and-belt system.
First internally regulated alternator used by GM. Mounting boss dimensions at the 10SI and 12SI are the same as with the previous externally regulated model 10DN Delco Remy alternator and so except for wiring the up-grade is a bolt-on. A very first look at a circuit diagram might be complex however if you can check out a subway map you can read schematics.
Wasnt into full production until about 1962.
The original 1960s GM alternator employs an external voltage regulator. The 10SI has three terminals including those with a 1 wire regulator. A typical 10Si series wiring diagram is illustrated in Figure 3. Replacing delco remy 10si 11si 12si or bosch k1 alternators with 11si alternator REPLACING SRE.
