Note:This is Similar to the 7565, With This Unit Adding an "I" Terminal. The 8028 (115A) and 7976 (100A) are Matches to the 8027, But in Lower Amp Versions. This is a 130A "Can Use" Unit for Many of the Lower Amp Units With a 1/4" B+ Stud, a Pin R-Terminal and Either No I-Terminal, or a 10-24 "I"-Terminal. Ignore Terminal(s) Not Needed. 7669 (145A) 1/4" B+ Pin "R" Terminal 10-24 "I" Terminal 6 Avalanche Diodes | This is the Same as the 240-849D, Except This Unit Uses the Later Rotor Shaft and the Larger Rear Bearing. This is a 130A "Can Use" Unit for Many of the Lower Amp Units With a 1/4" B+ Stud, a Pin R-Terminal and Either No I-Terminal, or a 10-24 "I"-Terminal. Ignore Terminal(s) Not Needed. 7669 (145A) 1/4" B+ Pin "R" Terminal 10-24 "I" Terminal 6 Avalanche Diodes The 22SI Unit With Specs Virtually the Same as This 21SI Unit is the 8075 (240-4007C). 22SI Units Have Improved Physical Characteristics Over the 21SI, as Well as the Autostart Trio Feature Not Used in the 21SI. This Should Be Considered if Using the 22SI In Place of the 21SI.
